Perhaps a maxInclusive of "INF"? (Disclaimer: haven't tried it) .micah -----Original Message----- From: Robin Berjon [mailto:robin.berjon@e...] Sent: Wednesday, February 04, 2004 8:22 AM To: max@m...

I believe I have one somewhere that's close to being good and that could exclude NaN. However it's several lines long (when wrapped) and last year it tended to crash validators. I can dig it up if you don't find a pleasant solution. -- Robin Berjon ----------------------------------------------------------------- The xml-dev list is sponsored by XML.org <http://www.xml.org>, an initiative of OASIS <http://www.oasis-open.org> The list archives are at http://lists.xml.org/archives/xml-dev/ To subscribe or unsubscribe from this list use the subscription manager: <http://lists.xml.org/ob/adm.pl>
