Pulling data from a constraint def

Hi:

I have a constraint defined on a table....

constraint design_style_is_invalid check (design_style in ('rls','sdp','rf','ssa','rom','rpt','analog','sdprpt','clkdist','global')),

Is there a way to get the valid values in the list from the metadata somehow?  Specifically, when someone hits this constraint, I want to not oonly tell them they entered an invalid value, but give them the list of valid choices at the same time.

I’d rather not put these in a table and implement with a foreogn key constraint for performance reasons. (Does that make sense?)
