This section contains the document level constraints for CDA documents that are compliant with this implementation guide.

The templates constrain the templates of a C-CDA document to accommodate the additional requirements introduced by the DS4P Project. For example, it constraints the General Header Constraints of a C-CDA document to require a complete accounting of the document provenance and to further require that the provenance of sections and entries should be specified if it differs from the information specified in the header of the document:
