Definitions for the sdc-questionnaire-initialExpression extension.
Guidance on how to interpret the contents of this table can be found here
| 0. Extension | |
| Definition | Initial value for a question answer as determined by an evaluated expression. |
| Short | Expression-determined initial value |
| Comments | Initial value is only calculated at the time the QuestionnaireResponse is first generated. |

| 4. Extension.url | |
| Fixed Value | http://hl7.org/fhir/uv/sdc/StructureDefinition/sdc-questionnaire-initialExpression |
| 6. Extension.value[x] | |
| Type | Expression, 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, Reference, TriggerDefinition, Quantity, uri, url, Annotation, ContactDetail, boolean, Signature, unsignedInt, time |

| 0. Extension | |
| Definition | Initial value for a question answer as determined by an evaluated expression. Optional Extension Element - found in all resources. |
| Short | Expression-determined initial valueOptional Extensions Element |
| Comments | Initial value is only calculated at the time the QuestionnaireResponse is first generated. |
| Control | 0..1* This element is affected by the following invariants: ele-1 |
| Is Modifier | false |
| Invariants | 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())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. |
| Short | ExtensionAdditional content defined by implementations |
| 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. |

| 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: |
| 4. Extension.url | |
| Definition | Source of the definition for the extension code - a logical name or a URL. |
| Short | identifies the meaning of the extension |
| 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. |
