I would personally recommend that the first applicable stylesheet
specified be used, and if that stylesheet is of a type that supports a
cascade mechanism, then all other applicable stylesheets of the same type
be used too.

So in the case above, style.css would be used, and the XSL sheet would be
ignored. (Since they are both persistent stylesheets, neither would appear
in the alternative stylesheet UI, leaving no way for the user to switch to
the XSL version.)

Per my description above, since XSL has no cascade mechanism (AFAIK), the
index.xsl sheet would be used and the transform.xsl sheet would be
dropped. Again, they are both persistent sheets so neither would be
available to the user.

BTW, regarding XSLT and alternate stylesheets: since it is possible for
the output of an XSLT transform to itself include stylesheets, potentially
pointing to yet more XSLT, the alternate stylesheets available at the
lower levels (e.g., the original document) may well end up being not
available to the user depending on the design of the UA.

This, once again, is undefined. :-)
