Dear Laura:

Well, it seems we've had too many cooks in the kitchen. I'm very, very
sorry. As Gregory notes in his message, we did assign him an action on
this at TPAC. Regretably, that action, along with several others from
TPAC, were logged in the WG tracker and not the TF tracker. I guess we
missed moving it back to TF. And, I clearly missed your email.

So, we probably don't need both change proposals before the WG. While
I've yet to read yours, I'm willing to bet there isn't likely a great
discrepency. Is there? I will take a look later today.

My suggestion is that we put our heads together and decide which one to
pull--assuming the differences are, in fact, cosmetic.

Janina
