0. Section
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.
Short | Base for all types and resources
Control | 10..1*
Is Modifier | false
Logical Container | ClinicalDocument (CDA Class)
Validation | Instance of this type are validated by templateId
XML Format | In the XML format, this property has the namespace `urn:hl7-org:v3`.
