Comment:

A codeable concept may have many codings.

This is a valuable feature, but it may be necessary to distinguish kinds of codings.

Precedence: It would be important to know whether one value is the original and another is a translation. (This may be the intent of "user-selected" but there may be no user-selected value.)

Precision may also be useful: some codings may be precise representations of the intent; others may be broader.

I recommend a relationship attribute.

This may be where to specify values suggested for 'user selected' above.
