[xsl] Getting the current node, in a different document

["David B" <daavidb@xxxxxxxxx>]

Hello,

I have two different documents, file1.xml and file2.xml, with similar
structure but different leaf nodes. I would like to do something like:

<xsl:for-each select="*[type='bar']">
   value 1: <xsl:value-of select="id">
   value 2: <xsl:value-of
select="document('file2.xml')/$current_xpath_in_file1/description">
</xsl:for-each>

But that is obviously not a valid xpath! How could a acheive the same
result using actualt xslt?

Best Regards,
/David
