PIDS11 — Value Sets for Coded data elements in the PID segment

Summary: PIDS specification has recommended the HL7 PID segment for standard trait names. The data type for many of the traits in the PID segment (like race, martial status etc.) are CE (Coded). An important aspect of achieving interoperatibility is to make a tight connection between coded fields and the coded vocabulary items that are possible values of the field. For example, the field "Sex" might have the allowable set of values: male, female and ambagious. To achieve that goal HL7 has defined value sets for the various coded fields. In most cases the values sets are from existing standard vocabulary like LOINC, UMLS etc. I was wondering - it will be nice if PIDS specifications also recommended the values sets for the coded fields in the PID segment to be the same as recommended by the HL7 standards.
