It isn't just w3schools that use the link
<?xml-stylesheet type="text/xsl" href=some_file.xsl"?>
- Michael Kay also uses it in his book "XSLT" 2nd edition. Most people regard this as a fairly definitive work.
Older versions of IE supported the working draft namespace for xsl because there wasn't anything else at the time - I don't think that was being stupid, I think it was being helpful, giving users a tool to experiment with. Present versions of IE use the correct namespace.
I found your comments regarding mime-types very interesting and from a brief read of the subject at IANA I see that you are right that text/xsl is not a recognised type. I shall look into this further.
