The if-absent() function is defined in the "Functions and Operators" document http://www.w3.org/TR/xquery-operators/ which both XSLT and XQuery are using as their core function library. The <xsl:value-of> instruction and its "separator" attribute are part of XSLT 2.0. Mike Kay XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
