But if there is no default namespace in CSS, then namespace treatment of "E" and "[A]" is very different. >> I don't think >> that special treatment of "*" as wildcard in ::attr(*) will do any harm. >> After all this behaviour can be brought back to attribute selectors -- >> "[*]" will match element that has at least one attribute. > > If attribute selectors allowed "[*]", it would match an element with > at least one attribute *in the null namespace* (to be consistent with > the behavior of plain attribute names). You'd have to write [*|*] to > select an element with any attribute whatsoever. Although I can follow you reasoning, I don't consider such behaviour of * really useful and logical. Probably due to my 15 years experience with XPath. :-) If you really think that having ::attr(*) for all attributes will result in dead kittens, let's move on and have ::attr() for choosing all attributes.
