Just so we're clear as to the scales here, the text/html environment consists of some 100 billion pages or so (to a first order approximation), while the application/...+xml universe consists of about 5 million pages. (This is based upon a study of several billion documents I did last year.) We should weigh the costs against those numbers before optimising for the XML case. > From my perspective, the cost of aria: in the text/html environment is > modest, manageable, and declining over time, whereas the cost of aria- > in the application/...+xml universe is large and permanent. The cost of aria: is that it puts up a huge barrier for migration from HTML to XML, thus reducing the value of the XML universe. The cost of aria- is that it makes the W3C look silly for having designed a namespace mechanism that it can't use. Which do we care more about? Migrating to XML, or not looking silly? -- Ian Hickson U+1047E )\._.,--....,'``. fL http://ln.hixie.ch/ U+263A /, _.. \ _\ ;`._ ,.
