Hi Jeni,

Thank you very much for explaining the "key issue" of xsl keys to me.
You were right, I had to compare the value of elementName (in the source
document) with elementName/@refAttr (in the other document); not the source
attribute refAttr.

It miraculously works now. I had some trouble understanding the mechanism
behind the "use" attribute.

Your help is greatly appreciated!

Greetings,
bas.alberts@xxxxxxxxxxxx
