Summary

Complex Extension: This extension applies to the Identifier data type and is used to represent HL7 V2 assigning authority details for HL7 V2 identification for routing.

- namespace-id: string: An Extension
- universal-id: string: Identifier values following the universal-id-type defined scheme.
- universal-id-type: string: Provides scheme to use to interpret the universal-id value .e.g. GUID, ISO etc. see HL7 V2 Table 0301 - Universal ID type.
