Also +1 on implementing the Berkeley parsing model in OpenNLP, but practically speaking, that's
a *ton* of work and I don't think anyone is going to do that any time soon. Jörn, please
correct me if I'm wrong.

What would Apache think about setting things up so that by default the OpenNLP parser was
used, but making it easy to substitute the Berkeley parser if a downstream user wants to (and
can accept the license requirements, and can add the dependency, etc.)?
