Subject RE: What we have so far
Date Tue, 18 Jul 2006 20:10:42 GMT
I don't think that anyone has actually tried to wire up the XML store
manager at runtime based on the code in the svn repository. Right now,
we're focussed mostly on getting the JDBC code drop ready, and so have
been neglecting any polishing / testing / etc. of the code that *is* in
the repo.
