Existing Wording \\Patient.communication

Comments
There is no way to specify the preferred communication (or language) for a patient. For an individual codeableConcept in the coomunication list, one of the Codings may be marked as primary but this does not indicate the primary communication. The primary on Coding only serves to indicate the 'original' or 'preferred' coding is a series of synonyms (ie. English expressed in two difference coding systems). You would not put english and Spanish in an individual communication item.

agree about primary. No opinion on the underlying language issue
