Logical Model: ED: EncapsulatedData (V3 Data Type)

Data that is primarily intended for human interpretation or for further machine processing outside the scope of HL7. This includes unformatted or formatted written language, multimedia data, or structured information in as defined by a different standard (e.g., XML-signatures.) Instead of the data itself, an may contain only a reference (see .) Note that the data type is a specialization of the data type when the media type is text/plain.

Usage:

• Use this Logical Model Profile: Act (CDA Class), Authenticator (CDA Class), CD: ConceptDescriptor (V3 Data Type), Criterion (CDA Class)...
