No, the first declaration is invalid (ssn should be in parentheses), and an XML element name/type must match the Name production and thus cannot begin with a number. Even if it were valid, this approach would mean his XML would look like this: <personalinfo> <ssn> <1/><1/><1/><2/><2/><3/><3/><3/><3/> </ssn> </personalinfo> XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
