Data Type Profile: HRex Identifier Reference Profile

This HRex Reference Profile is intended to be used by Da Vinci IGs where there is no expectation for a RESTful reference, but there is a need for a business identifier (and possibly a display name).

Usage:

• This DataType Constraint is not used by any profiles in this Implementation Guide
