[whatwg] Web Forms 2.0 proposal

[Sean Hogan]

I would request a input filter as a regex range eg a-zA-Z0-9
i.e.  if the keyCode is NOT within the range then preventDefault(). 

I imagine that number, date, datetime, etc will be special 
implementations that filter keyboard input. 
Why not extend the facility to text, etc?

cheers,
