Garsh, I've read that before.  Oh well, so I need to except SAX reality.
Does anyone know why Xerces might behave differently under WebSphere 4 with
Java 1.3 and Tomcat 5 with Java 1.4?  Why would it change?

This is all as it should be. Nothing surprising here. To the extent you 
are being surprised, it is by what the SAX spec requires and allows, 
rather than what Xerces is doing. See
