Qin,
	Thanks for the update.

To answer your question as well as respond to the related thread, as
chair, I generally think it best to adopt once there is consensus in the
WG on a direction to take with respect to the topic covered by a draft.
 That is not to say that a fully formed or documented solution is
required at adoption but that if there are several different approaches
available, that the adopted work reflects the direction that the WG will
pursue.

In this case, the current rev is certainly a step in that direction, but
the WG still as two different basic approaches available to it in this
draft and draft-bryskin-netconf-automation-yang.  I personally always
prefer it when individual draft authors can find common ground and come
to the WG with a single (unified) proposal rather than ask the working
group to choose one over the other.  I'm not sure who among the authors
will be in Singapore, but perhaps the authors can take the opportunity
to meet to discuss the possibly of such a unified proposal as well
report back to the working group on their progress/status.  Time
permitting, we should at least hear a summary of each approach so that
if a unified approach is not proposed that the WG is better informed on
the proposals.

Cheers,
Lou
