You can obviously say "cannot be empty" using minimum length constraints, but the actual constraint is "must contain at least one non-whitespace character" and as far as I'm aware there just isn't a way to say that without going to some pretty hairy regular expression facet stuff.  And as the man says, if you try and solve a problem with regular expressions well, now you have *two* problems.
