If you are serving XHTML content as application/xhtml+xml or a generic
XML media type like application/xml or text/xml then both Mozilla and
Opera 7 apply stylesheets linked in with an XHTML <link> element e.g.
<link xmlns="http://www.w3.org/1999/xhtml";
rel="stylesheet"
type="text/css"
href="style.css" />
there is no need to use the xml-stylesheet processing instruction. Those
browsers even apply XHTML
<style xmlns="http://www.w3.org/1999/xhtml"; type="text/css">...</style>
without any need to use an xml-stylesheet processing instruction. So as
long as you make sure you have the right namespace on your <link> or
<style> element there is no need to the processing instruction, in my
experience even if you use XML but not XHTML.
The page
http://www.w3.org/Style/styling-XML#Embedded
suggests that you can use an xml-stylesheet processing instruction with
a fragment identifier to link to some embedded CSS rules but so far
neither Opera nor Mozilla support that. Mozilla has a bug on that filed
but so far it has only brought up questions on whether/how that fragment
indentifier makes sense
