The simple answer is no. Jarno was suggesting you combine the 
files before XSLT processing but it appears you can't do that 
either. An alternative may be to create a variable holding just 
a copy of the items you want to index and use a key on that. I 
have seen problems on some processors doing this as it is really 
a side effect of allowing nodeset access to a result tree 
fragment which was not covered in the original standard. I would 
test it out first, something like this should help you determine 
if this will work. Although be aware this may not be portable 
between processors.

<xsl:key name="fookey" match="test" use="@id"/>

<xsl:variable name="foo">
	<test id='A'/>
	<test id='B'/>
	<test id='C'/>
</xsl:variable>

<xsl:for-each select="xalan:nodeset($foo)">
	<xsl:copy-of select="key('fookey','B')"/>
</xsl:for-each>
