Grammar pools with substitution groups broken in Xerces 2.10.
I was hoping to upgrade our application to use Xerces 2.10 in order to
get the fix for this issue:-
https://issues.apache.org/jira/browse/XERCESJ-1323
However our application doesn't work with Xerces 2.10 (we're currently
using 2.9.1). I think I've tracked down the problem to be the issue
logged here:-
https://issues.apache.org/jira/browse/XERCESJ-1463
I've tested against Xerces trunk (r1024302) and everything appears fine
there at least.
As I understand things this seems like quite a serious regression to me
as anyone using a grammar cache with schemas that use substitution
groups will hit problems. I was wondering if there's going to be a
maintenance release of the 2.10 code base to fix this? The revision
where this was fixed didn't apply cleanly to 2.10 so its probably going
to require someone who understands the changes to carefully review them.
If not 2.10.1 when are we likely to see 2.11?
Kind regards,
Chris Simmons.

It depends on what their grammar pool has already returned. If the grammar
being searched for is available in the local cache (a.k.a. grammar bucket)
they won't hit this issue.>

We've discussed [1] having a 2.11.0 release at the end of November.
