Issue

Within a clinical document it's sometimes useful to know when particular patient attribute values were valid. For example, an old MRN could be superseded by a new format, people frequently move to new addresses, women get married and change family names, etc.

CDA R2 supports the EN.validTime property for names, but it doesn't allow use of the HXIT generic type extension for II, AD, and TEL values. It would be nice if CDA R3 could support HXIT attributes for other data types.

Recommendation

In CDA R3, allow use of the HXIT.validTime property for all of the identity and demographic attributes of the Patient and Person RIM classes.
