Your expectation is substantiated, but Xalan does not (yet) support this neat feature. Check out the following page: Xalan-J 2.7.1: document() function disregards URI fragment identifier http://marc.info/?l=xalan-j-users&m=123866295117812 > ii.

You could help Xalan by doing the call once and storing the node-set in a variable: <xsl:variable name="my-uri" select="'some/relative/path/to/doc.xml'"/> <xsl:variable name="my-doc" select="document( $my-uri )/*"/> Hope this helps. -- Michael Ludwig
