So, if I undestand correct, there have been attempts to make it behave 
like the new validation attributes.
Thanks for sharing this info.
Can you tell us how it did break? Cause I don't see how it would really 
break, as now you just can't add any characters beyond the maxlength and 
otherwise you cannot submit if you do add more characters. Either way, 
any submitted value will therefore be within the given maxlength.

But hey, if it's not possible... no big deal, as it does have the same 
result for the submitted value.
