Re: MSXML4, key() across node-set

I think, this is a strange behaviour, too. Isn't only one nodeset created
with

<xsl:variable name="set" select="document(/files/node/@path)"/>
(You don't need the extension-function.)?

On which key('k-id',@id)[1] should only return the first node and always
return the same first node?

Only the working with a RTF and the nodeset-extension works as expected:
(I tried it with Xalan and MSXML.)

<xsl:variable name="settemp">
    <xsl:for-each select="/files/node">
        <xsl:copy-of select="document(@path)"/>
    </xsl:for-each>
</xsl:variable>

<xsl:variable name="set" select="xalan:nodeset($settemp)"/>

Is it correct how MSXML and Xalan behave?
