Yes. They are planned.

No news, other than:
- I'm not sure whether this should be done with
subscribers, adapters, or some combination. :)
- I've started down the road to a much more event-driven
publication model in my bobo branch:
This still isn't what you (and I want) wrt to output processing.
I really haven't had much time to think about this. My rough thinking
- The result of traversal should be adapted to a publiing interface
of some sort.
- The result of the above adaptation (or some method of the same) should
be called to produce a publishing result.
- The result of the call should then be adapted to some final interface.
The result of this adaptation should be handed to the response.
(Or maybe this step should be done by the response when it is
given the result of the call.)
I think this last step would allow you to hook something up.
<Jim waves hands ...)
I'd love to get suggestions if people have any ideas of how
this might work.
