(This is more of a request for more information than a bug report.)
This entry makes use of an <sdtc:id> element which is an extension to CDA R2. However Appendix C of PCC-TF which defines the extensions to CDA R2 doesn't mention the use of <sdtc:id> as a child of <cda:subject> or <cda:playingEntity> (just as a child of <sdtc:patient>). Could we have more information on how this extension is defined (or a link to where that definition occurs)? Thanks.
If subject is of type ParticipationTargetSubject, then to be compatible with CDA R2, the typeCode of subject should be SBJ not SUBJ.
