I think for normal purposes, the name you can give a constraint should be sufficient.
Else one can think of giving an error number as a name for the constraint and keep the description of the error number in a different table.

True, that would be nice.
Maybe a mode where the database would should all the constraints and not one be one.
By the, this way of handling the format of the data makes your database more independent from a script language. In fact you could use it in perl, java, asp, etc. and don't have to rewrite the whole constraints for submitting data again.
