Hi all,

IMO this is validator is not really application layer dependent, even  
thought this is
obviously where it will be most useful. Personally I would find something  
like SafeHtml
better than @WebSafe. It would also tie the constraints less to a layer.  
IMO it also communicates
its purpose better.

I think it is to early think about a new module/library. As said, I don't  
see this constraints
necessarily tied to a layer and without at least a couple of concrete  
layer specific constraints I
think we should wait.

My initial feeling is to wait for the next release, but I don't feel to  
strongly about this.
However, -1 for a new library/module and +1 for a rename of the constraint.
