Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).

  v: There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
requirements:
  v: Modifier extensions allow for extensions that *cannot* be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the [definition of modifier extensions](extensibility.html#modifierExtension).

comment:
  v: In resources, this is rarely used except for special cases where the representation deviates from the normal, and can only be done in the base standard (and profiles must reproduce what the base standard does). This element is used quite commonly in Logical models when the logical models represent a specific serialization format (e.g. CDA, v2 etc.).

definition:

comment:
  v: The concept SHALL be properly aligned with the data element definition and other constraints, as defined in the code system, including relationships, of any code listed here. Where multiple codes exist in a terminology that could correspond to the data element, the most granular code(s) should be selected, so long as they are not more restrictive than the data element itself. The mappings may be used to provide more or less granular or structured equivalences in the code system. This is used for both mapping to formal terminologies as well as to informal collections of data elements provided they can be treated as a 'system' (i.e. a single namespace with a canonical URI). For mappings to more complex structures not identifiable with a single id, use the ElementDefinition.mapping structure.
requirements:
  v: Links the meaning of an element to an external terminology, and is very useful for searching and indexing.

short:
  v: This element is sliced - slices follow
definition:
  v: Indicates that the element is sliced into a set of alternative definitions (i.e. in a structure definition, there are multiple different constraints on a single element in the base resource). Slicing can be used in any resource that has cardinality ..* on the base resource, or any resource with a choice of types. The set of slices is any elements that come after this in the element sequence that have the same path, until a shorter path occurs (the shorter path terminates the set).
comment:
  v: The first element in the sequence, the one that carries the slicing, is the definition that applies to all the slices. This is based on the unconstrained element, but can apply any constraints as appropriate. This may include the common constraints on the children of the element.

short:
  v: Base definition information for tools
definition:
  v: Information about the base definition of the element, provided to make it unnecessary for tools to trace the deviation of the element through the derived and related profiles. When the element definition is not the original definition of an element - e.g. either in a constraint on another type, or for elements from a super type in a snap shot - then the information in provided in the element definition may be different to the base definition. On the original definition of the element, it will be same.
comment:
  v: The base information does not carry any information that could not be determined from the path and related profiles, but making this determination requires both that the related profiles are available, and that the algorithm to determine them be available. For tooling simplicity, the base information must always be populated in element definitions in snap shots, even if it is the same.

  v: Identifies a profile structure or implementation Guide that applies to the datatype this element refers to. If any profiles are specified, then the content must conform to at least one of them. The URL can be a local reference - to a contained StructureDefinition, or a reference to another StructureDefinition or Implementation Guide by a canonical URL. When an implementation guide is specified, the type SHALL conform to at least one profile defined in the implementation guide.
comment:
  v: It is possible to profile backbone element (e.g. part of a resource), using the [http://hl7.org/fhir/StructureDefinition/elementdefinition-profile-element](https://build.fhir.org/ig/HL7/fhir-extensions/StructureDefinition-elementdefinition-profile-element.html) extension.

short:
  v: Specified value if missing from instance
definition:
  v: The value that should be used if there is no value stated in the instance (e.g. 'if not otherwise specified, the abstract is false').
comment:
  v: Specifying a default value means that the property can never been unknown - it must always have a value. Further, the default value can never be changed, or changed in constraints on content models. Defining default values creates many difficulties in implementation (e.g. when is a value missing?). For these reasons, default values are (and should be) used extremely sparingly. No default values are ever defined in the FHIR specification, nor can they be defined in constraints ("profiles") on data types or resources. This element only exists so that default values may be defined in logical models.

comment:
  v: Implicit meanings for missing values can only be specified on a resource, data type, or extension definition, and never in a profile that applies to one of these. An implicit meaning for a missing value can never be changed, and specifying one has the consequence that constraining its use in profiles eliminates use cases as possibilities, not merely moving them out of scope.

short:
  v: Value must have at least these property values
definition:
  v: Specifies a value that each occurrence of the element in the instance SHALL follow - that is, any value in the pattern must be found in the instance, if the element has a value. Other additional values may be found too. This is effectively constraint by example. When pattern[x] is used to constrain a primitive, it means that the value provided in the pattern[x] must match the instance value exactly. When an element within a pattern[x] is used to constrain an array, it means that each element provided in the pattern[x] must (recursively) match at least one element from the instance array. When pattern[x] is used to constrain a complex object, it means that each property in the pattern must be present in the complex object, and its value must recursively match -- i.e., 1. If primitive: it must match exactly the pattern value 2. If a complex object: it must match (recursively) the pattern value 3. If an array: it must match (recursively) the pattern value If a pattern[x] is declared on a repeating element, the pattern applies to all repetitions. If the desire is for a pattern to apply to only one element or a subset of elements, slicing must be used. See [Examples of Patterns](elementdefinition-examples.html#pattern-examples) for examples of pattern usage and the effect it will have.
comment:
  v: Mostly used for fixing values of CodeableConcept. In general, pattern[x] is not intended for use with primitive types, where is has the same meaning as fixed[x].

comment:
  v: Receivers are not required to reject instances that exceed the maximum length. The full length could be stored. In some cases, data might be truncated, though truncation should be undertaken with care and an understanding of the consequences of doing so. If not specified, there is no conformance expectation for length support.

definition:
  v: If true, implementations that produce or consume resources SHALL provide "support" for the element in some meaningful way. Note that this is being phased out and replaced by obligations (see below). If false, the element may be ignored and not supported. If false, whether to populate or use the data element in any way is at the discretion of the implementation.
comment:
  v: "Something meaningful" is context dependent and impossible to describe in the base FHIR specification. For this reason, the mustSupport flag is never set to true by the FHIR specification itself - it is only set to true in profiles. A profile on a type can always make mustSupport = true if it is false in the base type but cannot make mustSupport = false if it is true in the base type. This is done in [Resource Profiles](profiling.html#mustsupport), where the profile labels an element as mustSupport=true. When a profile does this, it SHALL also make clear exactly what kind of "support" is required, as this can mean many things. Note that an element that has the property IsModifier is not necessarily a "key" element (e.g. one of the important elements to make use of the resource), nor is it automatically mustSupport - however both of these things are more likely to be true for IsModifier elements than for other elements.

definition:
  v: If true, the value of this element affects the interpretation of the element or resource that contains it, and the value of the element cannot be ignored. Typically, this is used for status, negation and qualification codes. The effect of this is that the element cannot be ignored by systems: they SHALL either recognize the element and process it, and/or a pre-determination has been made that it is not relevant to their particular system. When used on the root element in an extension definition, this indicates whether or not the extension is a modifier extension.
comment:
  v: Only the definition of an element can set IsModifier true - either the specification itself or where an extension is originally defined. Once set, it cannot be changed in derived profiles (except in the special case of the defining a new extension). An element/extension that has isModifier=true SHOULD also have a minimum cardinality of 1, so that there is no lack of clarity about what to do if it is missing. If it can be missing, the definition SHALL make the meaning of a missing element clear. See further discussion in the [conformance rules](conformance-rules.html#isModifier) section.

comment:
  v: Some resources include a set of simple metadata, and some very large data. This element is used to reduce the quantity of data returned in searches. Note that servers may pre-cache summarized resources for optimal performance. When a request is made with _summary=true, serializers only include elements marked as 'isSummary = true'. With a few exceptions (listed below), all datatype properties are included in the summary form. In resource and datatype definitions, if an element has a descendant within the same StructureDefinition marked as isSummary=true or if it satisfies both of the following conditions, it must be marked as isSummary=true: * is at the root or has a parent that is 'mustSupport' * has a minimum cardinality of 1 or is a modifier element The following datatype properties are exceptions, and are not marked as isSummary: * Attachment.data * Signature.data, Signature.targetFormat, Signature.sigFormat * Narrative.status, Narrative.div * SampledData.data.

comment:
  v: There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

comment:
  v: The concept SHALL be properly aligned with the data element definition and other constraints, as defined in the code system, including relationships, of any code listed here. Where multiple codes exist in a terminology that could correspond to the data element, the most granular code(s) should be selected, so long as they are not more restrictive than the data element itself. The mappings may be used to provide more or less granular or structured equivalences in the code system. This is used for both mapping to formal terminologies as well as to informal collections of data elements provided they can be treated as a 'system' (i.e. a single namespace with a canonical URI). For mappings to more complex structures not identifiable with a single id, use the ElementDefinition.mapping structure.

  v: This element is sliced - slices follow
definition:
  v: Indicates that the element is sliced into a set of alternative definitions (i.e. in a structure definition, there are multiple different constraints on a single element in the base resource). Slicing can be used in any resource that has cardinality ..* on the base resource, or any resource with a choice of types. The set of slices is any elements that come after this in the element sequence that have the same path, until a shorter path occurs (the shorter path terminates the set).
comment:
  v: The first element in the sequence, the one that carries the slicing, is the definition that applies to all the slices. This is based on the unconstrained element, but can apply any constraints as appropriate. This may include the common constraints on the children of the element.

  v: Base definition information for tools
definition:
  v: Information about the base definition of the element, provided to make it unnecessary for tools to trace the deviation of the element through the derived and related profiles. When the element definition is not the original definition of an element - e.g. either in a constraint on another type, or for elements from a super type in a snap shot - then the information in provided in the element definition may be different to the base definition. On the original definition of the element, it will be same.
comment:
  v: The base information does not carry any information that could not be determined from the path and related profiles, but making this determination requires both that the related profiles are available, and that the algorithm to determine them be available. For tooling simplicity, the base information must always be populated in element definitions in snap shots, even if it is the same.

short:
  v: Specified value if missing from instance
definition:
  v: The value that should be used if there is no value stated in the instance (e.g. 'if not otherwise specified, the abstract is false').
comment:
  v: Specifying a default value means that the property can never been unknown - it must always have a value. Further, the default value can never be changed, or changed in constraints on content models. Defining default values creates many difficulties in implementation (e.g. when is a value missing?). For these reasons, default values are (and should be) used extremely sparingly. No default values are ever defined in the FHIR specification, nor can they be defined in constraints ("profiles") on data types or resources. This element only exists so that default values may be defined in logical models.

comment:
  v: Implicit meanings for missing values can only be specified on a resource, data type, or extension definition, and never in a profile that applies to one of these. An implicit meaning for a missing value can never be changed, and specifying one has the consequence that constraining its use in profiles eliminates use cases as possibilities, not merely moving them out of scope.

short:
  v: Value must have at least these property values
definition:
  v: Specifies a value that each occurrence of the element in the instance SHALL follow - that is, any value in the pattern must be found in the instance, if the element has a value. Other additional values may be found too. This is effectively constraint by example. When pattern[x] is used to constrain a primitive, it means that the value provided in the pattern[x] must match the instance value exactly. When an element within a pattern[x] is used to constrain an array, it means that each element provided in the pattern[x] must (recursively) match at least one element from the instance array. When pattern[x] is used to constrain a complex object, it means that each property in the pattern must be present in the complex object, and its value must recursively match -- i.e., 1. If primitive: it must match exactly the pattern value 2. If a complex object: it must match (recursively) the pattern value 3. If an array: it must match (recursively) the pattern value If a pattern[x] is declared on a repeating element, the pattern applies to all repetitions. If the desire is for a pattern to apply to only one element or a subset of elements, slicing must be used. See [Examples of Patterns](elementdefinition-examples.html#pattern-examples) for examples of pattern usage and the effect it will have.
comment:
  v: Mostly used for fixing values of CodeableConcept. In general, pattern[x] is not intended for use with primitive types, where is has the same meaning as fixed[x].

short:
  v: Minimum Allowed Value (for some types)
definition:
  v: The minimum allowed value for the element. The value is inclusive. This is allowed for the types date, dateTime, instant, time, decimal, integer, and Quantity.
comment:
  v: Except for date/date/instant, the type of the minValue[x] SHALL be the same as the specified type of the element. For the date/dateTime/instant values, the type of minValue[x] SHALL be either the same, or a [Duration](datatypes.html#Duration) which specifies a relative time limit to the current time. The duration value is positive, and is subtracted from the current clock to determine the minimum allowable value. A minimum value for a Quantity is interpreted as a canonical minimum - e.g. you cannot provide 100mg if the minimum value is 10g.
