I forget to mention in my previous post: I've run Oxygen XML Author with oxygenDebug.bat and with the log4j.properties specified on the Oxygen website (to write logs under my desktop), but the only error I see when I use "my" .jar is the same one I get when there is no datatype .jar present:
E [Jing] datatype library "http://whattf.org/datatype-draft" not recognized
It's as if my .jar is being ignored. This is partly what prompted my niggling thought that perhaps Oxygen has some persistent parser cache that expects the other jar (from the jEdit XML plugin developer that I used first); but if so, the stickiness is deeper than just the .jar file name, because I get the same behavior when I use the same .jar file name. If I close Oxygen, replace my .jar with the .jar from the jEdit XML plugin developer, and restart Oxygen, then I don't get that Jing error, and validation works using the v.Nu schemas that refer to those datatypes. I need to investigate whether I can turn on additional diagnostic options for Jing that might indicate whether or not my .jar is being used. I'd appreciate advice on that. (I've had confirmation from the jEdit XML plugin developer that all he did was to cut down the vnu.jar.)
