Not trying to sum this thread, my learning point, partly answering Jim's question do we need exslt function, seems to be Mikes ($x castable as xs:XXX) either alone, or in a <xsl:choose> within a function, returning whatever is appropriate to the need. That seems to fit the bill IMHO. regards DaveP. -- DISCLAIMER: NOTICE: The information contained in this email and any attachments is confidential and may be privileged.
