0. Component
Definition

Defines the basic properties of every data value. This is an abstract type, meaning that no value can be just a data value without belonging to any concrete type. Every concrete type is a specialization of this general abstract DataValue type.


Base definition for all types defined in FHIR type system.

4. Component.realmCode
Definition

When valued in an instance, this attribute signals the imposition of realm-specific constraints. The value of this attribute identifies the realm in question

Control0..*
Typehttp://hl7.org/cda/stds/core/StructureDefinition/CS
6. Component.typeId
Definition

When valued in an instance, this attribute signals the imposition of constraints defined in an HL7-specified message type. This might be a common type (also known as CMET in the messaging communication environment), or content included within a wrapper. The value of this attribute provides a unique identifier for the type in question.

8. Component.templateId
Definition

When valued in an instance, this attribute signals the imposition of a set of template-defined constraints. The value of this attribute provides a unique identifier for the templates in question
