I pulled latest release for each subsystem and can get them to build,
although tests don't pass again.

I now have SignatureConstants class which is good.

I notice there are some changes which now break startup/initialization.
This may be because we are using xerces 2.7.1 (I will try 2.9.0) but it
seems like coding error. I am looking into it.
