1. Extension
Definition | A reference to an alternative point of contact (NatlDirEndpointQry-PractitionerRole, NatlDirEndpointQry-Organization, NatlDirEndpointQry-OrganizationAffiliation, or NatlDirEndpointQry-Location) for this organization Optional Extension Element - found in all resources.
2. Extension.extension
Control | 0..0*
3. Extension.url
Fixed Value | http://hl7.org/fhir/us/directory-query/StructureDefinition/via-intermediary
4. Extension.value[x]
Control | 10..1
Type | Choice of: (NatlDirEndpointQryPractitionerRole|NatlDirEndpointQryOrganizationAffiliation|NatlDirEndpointQryLocation|NatlDirEndpointQryOrganization), date, Meta, Address, Attachment, integer, Count, DataRequirement, Dosage, uuid, Identifier, Coding, SampledData, id, positiveInt, Distance, Period, Duration, canonical, Range, RelatedArtifact, base64Binary, UsageContext, Timing, decimal, CodeableConcept, ParameterDefinition, dateTime, code, string, Contributor, oid, instant, ContactPoint, HumanName, Money, markdown, Ratio, Age, TriggerDefinition, Quantity, uri, url, Annotation, ContactDetail, boolean, Expression, Signature, unsignedInt, time

1. Extension
Definition | A reference to an alternative point of contact (NatlDirEndpointQry-PractitionerRole, NatlDirEndpointQry-Organization, NatlDirEndpointQry-OrganizationAffiliation, or NatlDirEndpointQry-Location) for this organization Optional Extension Element - found in all resources.
Control | 0..* This element is affected by the following invariants: ele-1
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists())
2. Extension.extension
Definition | An Extension May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. 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.
Control | 0..0*
Type | Extension
Alternate Names | extensions, user content
Comments | 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.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists())
Slicing | This element introduces a set of slices on Extension.extension. The slices are unordered and Open, and can be differentiated using the following discriminators: value @ url
3. Extension.url
Definition | Source of the definition for the extension code - a logical name or a URL.
Control | 1..1
Type | uri
XML Representation | In the XML format, this property is represented as an attribute.
Comments | The definition may point directly to a computable or human-readable definition of the extensibility codes, or it may be a logical URI as declared in some other specification. The definition SHALL be a URI for the Structure Definition defining the extension.
Fixed Value | http://hl7.org/fhir/us/directory-query/StructureDefinition/via-intermediary
4. Extension.value[x]
Definition | Value of extension - must be one of a constrained set of the data types (see Extensibility for a list).
Control | 10..1
Type | Choice of: Reference(NatlDirEndpointQryPractitionerRole|NatlDirEndpointQryOrganizationAffiliation|NatlDirEndpointQryLocation|NatlDirEndpointQryOrganization), date, Meta, Address, Attachment, integer, Count, DataRequirement, Dosage, uuid, Identifier, Coding, SampledData, id, positiveInt, Distance, Period, Duration, canonical, Range, RelatedArtifact, base64Binary, UsageContext, Timing, decimal, CodeableConcept, ParameterDefinition, dateTime, code, string, Contributor, oid, instant, ContactPoint, HumanName, Money, markdown, Ratio, Age, TriggerDefinition, Quantity, uri, url, Annotation, ContactDetail, boolean, Expression, Signature, unsignedInt, time
