ah...
i see, u could use the following using system-property, which should get u
the XSLT processor also ( using
<xsl:stylesheet version="1.1"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:template match="/">
<xsl:choose>
<xsl:when test="system-property('xsl:version') >= 1.1">
<xsl:exciting-new-1.1-feature/>
</xsl:when>
<xsl:otherwise>
<html>
<head>
<title>XSLT 1.1 required</title>
</head>
<body>
<p>Sorry, this stylesheet requires XSLT 1.1.</p>
</body>
</html>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
check out here

otherwise, we live in a world where there are only 2 browsers handling this,
u may find having an overarching solution of client detection, then just
XSLT processor detection will be more desirable instead of having 2 seperate
systems.
btw if u are worried about keeping the logic in xml/xlst u could modify

to always go to the same URL ( lets say main.xml ) yet inject a parameter,
then use xsl:param to make the decision...but then u would probably have to
have browser specific code to handle the transform
gl, jim fuller
btw any one else experience IE not respecting Content-Type so rudely ?
