It seems that the <xml>-tag is something special in IE6 and it keeps the
<xml>-tag and content inside the <head>.

I'm really loathe to add such a quirk. I cast a vote for WONTFIX/evangelism.
As long as this is not a common "data islands" technique or something, I agree.
This isn't something I have been tracking when trolling the web, but will add it
to my list. I'm in the middle of a multiday run now, so don't expect answers
until next week.
Bob, any luck?

Maybe it's at least worth it to add XML to the hidden elements in html.css.

I forgot. I will start a scan today. Sorry.

Unfortunately, that won't help this case since we don't treat userdefined tags as containers in the HEAD section of a document. The reason the text is showing up is that the <xml> tag isn't containing it and keeping it in the head. Fixing this might require adding a new "xml" element.

Someone should feel free to resummarize better than my new summary.
Summary: Firefox can't render that URL properly. → <xml> tags in the head do not hide their content
this is _so_ wontfix...
Okay. Bob, if you get numbers on this to show that it's something we really should consider, put them here. Otherwise, I'll follow Ian's request.

Note the easy workaround from a web site's point-of-view would be to have an |xml { display: none}| style somewhere and to move the <xml> tag into the BODY.
