that would only match id data was the document element, and uses the
string value of the whole document as key.


keys apply (conceptually) to all files so

 <xsl:key name="TOPIC" match="data[@name='WDtopicID']" use="."/>

You need to specify the document at this point

key('TOPIC',, 'dan1370798005424',$QAREPORT)"/>

or in XSLT1

$QAREPORT/key('TOPIC', 'dan1370798005424')
