Data Type Profile: Identifier DataType Profile (CA Baseline)

This profile constrains the identifier data type to support minimum expectations of Canadian systems when expressing the identifier data type.

Usage:

• Use this DataType Constraint: Patient Profile, Practitioner Profile (Provider Registry), Practitioner Profile (General), PractitionerRole Profile (Provider Registry) and PractitionerRole Profile (General)
