I installed XP SP2 RC2 last weekend (mostly to get DHTML Menu 4 working) and overall it is a big disappointment… but today I realized that it does not ask me to save XHTML (application/xhtml+xml) files anymore but it actually shows it. Does this mean that IE in SP2 will support XHTML? Unfortunately IE still does not support XHTML correctly. Modifying the XHTML file so that it no longer is well formed gives no XML parse error.
I’m not yet sure whether I like this new behavior. It is obvious that this will lead to troubles where people only test their pages in IE. Why doesn’t Microsoft test for wellformedness? That should be trivial to do.
