For a while I've been aware that there is a problem with including the XML prolog (<?xml version="1.0"?>) in XHTML documents, but nobody has explained what it was and I didn't bother to go looking. However, it puts IE 6 into "render like IE 5" mode which seems pretty dumb, however, it answers a few questions.

I will be removing the prolog from the pages on this site sometime soon.

The XML prolog, as I understand it, is not required anyway - someone (Zeldman, Bluerobot - one of that ilk) wrote about ditching it as fast as your little delete key can carry you. Probably for the same reason that you did.
