             <xd:p><xd:b>Purpose:</xd:b> Provides general purpose display of CDA release 2.0 and 2.1 (Specification: ANSI/HL7 CDAR2) and CDA release 3 (Specification was pulled after ballot) documents. It may also be a starting point for people interested in extending the display. This stylesheet displays all section content, but does not try to render each and every header attribute. For header attributes it tries to be smart in displaying essentials, which is still a lot.</xd:p>
