Once this patch is applied it will not be a problem:

http://sourceforge.net/patch/?func=detailpatch&patch_id=101514&group_id=5470

prepareParser becomes essentially a no-op.

You are right, the published interface isn't up-to-date. That's
basically a documentation issue. You could submit a patch but I think
Lars is still going to change those method signatures next week.

Since you understand things so well, maybe you could do me a favor and
try pulldom and see if it meets your needs. The interface is very
static, and very extensible so future extensions to XML should not break
it. We are deciding whether to make pulldom an official API and your
opinion would help.
