Validation Support

[John Hendrikx]

Hi Dirk,

That is a very nice framework, and although I wouldn't be against its 
inclusion in FX, I'm more wondering if JavaFX could do more to help make 
tools like ValidatorFX easy to build.

I'm not quite sure how one can use not having validation as an argument 
against using FX, when there clearly are free alternatives available.  
Surely not everything can or should be part of the base framework?  A 
line must be drawn somewhere, especially when there are very few core FX 
developers.

I'd much rather see work being done on things that can't be provided by 
3rd parties, preferably by opening up more parts of FX with well 
specified API's.
