Hi,
historically, UAs have only supported "text/xsl", which never was
registered as media type for XSLT.
For now, IE9 seems to be the only shipping UA that understand the
registered media type -- application/xslt+xml -- as well.
In Firefox, this was just fixed, and might ship with Firefox 7 (*) (see
<https://bugzilla.mozilla.org/show_bug.cgi?id=231395>).
For Chrome / Safari / Opera I don't have any information about whether
there are plans to add support -- feedback appreciated.
Best regards, Julian
(*) Sounds scary, but actually means "end of year".
