Existing Wording:

This definition establishes the local name "Female Administrative Sex" as a reference to the external identifier for the valueset, an Object Identifier (OID) in this case: 'urn:oid:2.16.840.1.113883.3.560.100.2'. The external identifier need not be an OID, it may be a uniform resource identifier (URI), or any other identification system. CQL does not interpret the external id, it only specifies that the external identifier be a string that can be used to uniquely identify the valueset within the implementation environment.
