Minimal DocumentReference

This is the most basic MHD DocumentReference object. It contains the attributes required by XDS and by FHIR and includes nothing extra. This has been validated with the FHIR schema but not yet tested against any of the FHIR test servers.

Sorry for the horrible use of codes but remember that famous quote from Star Trek (with apologies): Darn-it Jim, I'm an engineer, not a doctor.
