Data Type Profile: HRex REST Reference Profile

This HRex Reference Profile is intended to be used by Da Vinci IGs where there is a need for the reference to be resolvable via REST (and potentially chained through).

Usages:

• Use this DataType Profile: HRex Parameters - Member Match Response Profile
