Unfortunately, you're correct that there's no way for you to access the schema metadata at present. Longer-term I'd like to standardize the schema code generation model and expose it as an official API, but it'll take a substantial refactoring before I'm ready to do that.
That said, it should be possible to incorporate the restrictions directly into the code generation without major changes, but it'll still take some work. One issue is in how to actually implement the validation. JSR 303 is now official, but I haven't looked into how easy or difficult it is to use this in different production environments. It also looks like JSR 303 only handles validation calls, rather than supporting fast-fail validate-on-set checks. I'd like to allow users to choose between validate-on-set checks (which would throw a runtime exception if you tried to set a non-allowed value to a property) and validate calls (which could be used for post-set and pre-get validation checks), but if I had to choose one way or the other I'd go with the fast-fail validate-on-set approach (since that forces you to deal with the problem at its source, rather than trying to backtrack from an invalid state detected later). - Dennis Dennis M.
