The modeling of raceCode/sdtc:raceCode has always been a bit confusing. When do multiple elements mean bi-racial vs just storing more details? Would prefer to see raceCode correspond 1:1 with what systems are recording in Race fields, where multiple elements indicates multiple races.

Proposal: update raceCode and sdtc:raceCode to be bound to raceCategory, and add a translation with a binding to Detailed Race. To look something like this:

Example structures of race would be:

<raceCode code="2106-3" displayName="White">
  <translation code="2113-9" displayName="Irish" />
</raceCode>
<sdtc:raceCode code="2106-3" displayName="White">
  <translation code="2112-1" displayName="German" />
</sdtc:raceCode> 

or:

<raceCode code="2106-3" displayName="White" />
<sdtc:raceCode code="1002-5" displayName="American Indian or Alaska Native">
  <translation code="1004-1" displayName="American Indian" />
</sdtc:raceCode>
