Using of extensions

["Voytenko, Dimitry" <DV...@SECTORBASE.COM>]

Does anyone wrote extensions that return result-tree-fragments. For instance
I have xslt fragment
<xsl:variable name="test">
	<my-ext:execute/>
</xsl:variable>

in the case my-ext:execute returns elements so they can be used further for
instance with nodeset extension

<xsl:for-each select="Nodeset:nodeset($test)/tagx">
	............
</xsl:for-each>
