>So, according to the comments on the first answer in this StackOverflow post, it appears that there is nothing included to perform client-side validations of model level attributes. This seems like a much bigger oversight than the other things I’ve seen missing.
And, now, I don’t believe I can use the built-in validations. It’s just is too limited, has too many capabilities missing, and too many work-arounds feel so much like hacks that I’m going to go back to the jquery validation library.
