By the far the most portable and cleanest solution is to pass the URL of
the document that contains the data, then let the document() function load
it:
<?xml version="1.0"?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:param name="paramsURI" select="''") />
<xsl:variable name="params" select="document($paramsURL)" />
<xsl:template match="/">
<xsl:copy-of select="$params/Params/[EMAIL PROTECTED]'t1']" />
</xsl:template>
</xsl:stylesheet>
This assume you're going to use XPath to search the parameters. If that's
not what you're doing, this solution may not be appropriate.
