Authors,

This draft is a nice piece of work!

What do you think about a few other cases? In particular, there are some 
other kinds of glare that I don't think many people have considered:

Your draft covers re-INVITE crossover, but there is also the possibility 
of UPDATE crossover and re-INVITE/UPDATE crossover. And these are 
subtlely different from one another:

- I don't believe UPDATE crossover is an error unless both contain
   an offer
- re-INVITE/UPDATE crossover is probably not an error unless the
   UPDATE contains an offer.

	Thanks,
	Paul
