Am I correct that element substitution will not work well unless XSLT processor is schema aware but type substitution will? AFIK, there are *NO* open source, royalty free schema aware XSLT processors available. It seems that this would make type substitution a better fit for open source, royalty free non-schema-aware XSLT processors available. -- Regards, Farrukh Najmi Web: http://www.wellfleetsoftware.com
