RE: [xsl] Assigning a dynamic value of href in a stylesheet PI

as others already pointed out you could say 
<xsl:processing-instruction name="xml-stylesheet">
href="<xsl:value-of select="concat($client,'-part-styler.xsl')"/>"
type="text/xsl"
</xsl:processing-instruction>

however I have to wonder if maybe instead of passing in stuff like ie5
or netscape as the value of your $client if you shouldn't try to
discover some common condition to your clients, i.e have a class of
clients, as it would no doubt make it easier to code.
Also you can check for your processor inside your stylesheet with 
function-available()

I don't know I've always been able to find that the HTTP_USER_AGENT
contains Netscape if I get a Netscape browser, I can't be more specific
than that without knowing your environment. Browse to this site for
examples of various user_agent strings:
