Sure. Just read on ....

There's a few things on the XMLContext/Unmarshaller/Marshaller side of
things that are currently not exposed through OXM's CastorMarshaller. SO
the project would be split between an analysis phase (what's actually
missing?) and an actual implementation.

Correct, the idea here is simple, the implementation might be a bit more
complex. As you noticed already, currently OO--> XML transformation is
supported through SAX events (streaming) only. In order to support StAX
as well, quite some refactoring will be required.
I am actually not sure what classes will be affected, but at minimum a
little 'layer' will be required that is capable of using any of the
underlying XML technologies. Does this make sense ?

Well, you do not have to send a patch that actually provides an
implementation, as that's the actual work you are meant to be doing
during GSoC. But such a patch could f.e. have - at the very minimum -
comments in side that identify the code fragments where things will need
to change. Or if you went about the idea mentioned above (adding a
layer), such patch could include pseudo code wrt this layer, etc.

No, but we expect this to be part of the proposal, so that we can make
well informed decisions about your proposals. Now, if you gave us a
patch on the very last day, it would be a pity.
Why not look at this as an incremental process by which we try to assess
your skills (Java, coding, software engineering) and your enthusiasm.
> Do You treat this as obligatory?
Yes, pretty please. It's not so much about a perfect proposal/patch, but
more about you engaging with us/the project, and show us that you
actually mean it.

Well, we are available in various ways: email, irc, ....
Kind Regards
