Mechanics of enhancing Java taming database?

I tried asking before on April 1, but I had just joined and it was around the time of the spam uptick.  I'll try again, with fewer questions this time.

If one wished to help enhance the Joe-E SafeJ database, what would the recommended mechanics be?  That is, should I check out the Subversion repository for Joe-E, edit one or more .safej files in the safej directory, make a diff/patch, and email it to this email list?  Or would some other method be preferable?

Is this same SafeJ taming database also used for taming the Java library for other E variants, such as E-on-Java?  For creating the documentation at http://erights.org/javadoc/index.html ?

Or is there some other way to make such careful review of the Java library available to as many variants of E as possible?

Thanks,
