If you modeled a string as a sequence of characters, then to have a sequence of strings you would need to allow sequences of sequences; and then you would need to distinguish between an empty sequence and a sequence whose only member was an empty sequence. You can't get rid of the problem that easily! Mike Kay XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
