Definitions for the Section logical model.
Guidance on how to interpret the contents of this table can be foundhere
| 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. |
| 2. Section.nullFlavor | |
| Definition | If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing. |
| Control | 0..1 |

| 6. Section.typeId | |
| Definition | When valued in an instance, this attribute signals the imposition of constraints defined in an HL7-specified message type.
