Bill,
Answers to your questions below:

The good news is that you don't need to setup anything. Those factories are setup automatically by reading processors.xml. I tried to declare a processor with xmlns:wynn="com:wynnon:oxf:processors" and this is working fine. It is almost as if your processor.xml was not read.

Good questions. I guess this will sound stupid, but did you restart your servlet container after the changes, and did you double-check that orbeon.jar contains your latest and greatest processors.xml, or that you don't have more than one processors.xml, for example one in orbeon.jar and one under classes?

This absolutely makes sense. A first solution (that may change in the future) is checked in and will show up soon in the unstable builds. You can create a file called custom-processors.xml under the config directory. This file has the same format as the regular processors.xml.
Note that you will still need to restart your servlet container after changes to custom-processors.xml, because the XInclude mechanism doesn't detect changes to included resources yet.
