You might want to create a __minimal__ sample program and sample inputs
that reproduce the problem.  Be certain this sample program has no external
dependencies.  You can then create a bug report in Bugzilla and attach the
files necessary to reproduce the problem.  Someone will take a look at it.

That question has nothing to do with Xalan.  We don't know how your
application works, or what your code looks like, so how can we answer that
question?  There are many ways you might keep those objects in-scope.

This is an open source project, so anyone willing to write documentation
can contribute it back.
