XML Schema Reimplementation of a subset of the Abstract Data Type Specification of HL7v3 (ANSI/HL7 V3 DT, R1-2004; HL7 Version 3 Standard: Data Types - Abstract Specification, Release 1 - 11/29/2004) by InterComponentWare AG. Limited to the data types needed to express a patient's privacy consent directive using XACML, as specified in the IHE Advanced Patient Privacy Consent (APPC) Profile. The standard v3 XML schemas are to complex for easy integration, therefore we created this subset.
