The existing practitioner resource has 0..1 organisation, the organization the practiioner represents

In RIM terms, this is an entity playing a role scoped by an organization entity

This doesn't match the way people actually implement practitioner in their systems - a single record for the person, with relationships to multiple organizations. Forcing organizations to clone the practitioner record for different organisations has disastrous effects on mappings, on audit trails, on maintenance procedures, and on basic sense.

This needs to be fixed so that a single practitioner has multiple associations with organizations. So: make organiation a complex element, and move period, telecom and address in there. And maybe role

Note: why isn't this a problem in CDA? because people just name whatever organisation is relevant for the practitioner a the time, but provide the same identifier each time. This implicitly violates the RIM semantics, but is not testable.
