| 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. | 
| Short | Base for all types and resources |

| Invariants | body-choice: Choice of the body required. ( (nonXMLBody | structuredBody).count() = 1) | 
| 2. Component.nullFlavor | |
| Definition | If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing. |

| XML Format | In the XML format, this property is represented as an attribute. | 
| Label | Exceptional Value Detail | 
| 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 | 
| Control | 0..* | 
| Type | http://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. | 
| Control | 0..1 |

| 10. Component.typeId.assigningAuthorityName | |
| Definition | A human readable name or mnemonic for the assigning authority. The Assigning Authority Name has no computational value. The purpose of a Assigning Authority Name is to assist an unaided human interpreter of an II value to interpret the authority. Note: no automated processing must depend on the assigning authority name to be present in any form. |
