[RT/OT?] Custom datatypes and validation for RelaxNG

[Sylvain Wallez]

I just found a very interesting article [1] showcasing the datatype 
extension API of RelaxNG [2] which I wasn't aware of. It includes both 
parsing and validation.

Although the ValidationContext class is limited (having named attributes 
would allow for abitrary extension), I'm wondering if this can be used 
in some way in CForms.

Just some saturday morning thoughts...
