| 0. Reference | |
| 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. |

| XML Format | In the XML format, this property has the namespace urn:hl7-org:v3. |

| 6. Reference.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. |
