I wasn't involved but presumably because that would lead people to think that the attribute value mattered and that disabled="no" meant something different from disabled="yes". The point about boolean attributes as interpreted by browsers is that they are true if they are there (with any value) and false if they are not there. so in html you have <foo> and <foo disabled> as markup, in XML where you need to supply a value, disabled="disabled" is valid for legacy reasons, disabled="" is valid because that's what people thought the syntax was anyway and anything else including disabled="no" acts the same way as disabled="" but is classed as non conforming (which only matters to validators not to browsers) David -- google plus: https:/profiles.google.com/d.p.carlisle ________________________________________________________________________ The Numerical Algorithms Group Ltd is a company registered in England and Wales with company number 1249803.
