Thanks everyone for feedback, it's appreciated. @Carol - Thanks for checking, good to know I'm not reinventing the wheel... At least wheels coming from Adobe that is.
@Michael - I was wondering about what exactly I'd have to hook into last night as I was reading GlobalizationValidatorBase, but it was 2 am and it was the first time I'd seen this class, my previous validators are MX. Did you ever figure out how it ties in? I'm going to mess with it some more tonight. -omar
