Greetings, In attempting to write a javascript implementation of Web Forms 2.0 attributes, I came across a stumbling block. At times, form validation requires a "not pattern" result, i.e. if a certain pattern matches the element value, the validation engine should return an error. The best real-world example of this type of implementation would be a form field with an initial value that must be changed in order to be processed as valid. I would suggest an attribute name notPattern, implemented as a reverse of the pattern attribute. e.g.: <input type="text" required="required" notPattern="First Name\s*" value="First Name" /> I hope it is not too late in this versions timeframe to bring such functionality in, as it seems impossible right now. -- Ryan Cannon Wordslinger, Webwright http://RyanCannon.com
