minor <lock> ambiguity

Hi,

prot-12:sec. 7.5, para 2 says a lock request must fail
if "an existing session" hold the lock.

para 6, bullet 2 says a lock must not be granted
if "another NETCONF session" holds the locks.

Issue:  Does the agent need to check for the corner-case
where the manager is calling lock multiple times,
or is the agent strict and treat this as an error?

I remember we discussed this issue in the past, but I
don't remember making a decision:

Is it an error if a session call <lock> on a config
that it already locked?  This is probably a programming
error on the NMS, so IMO a lock-denied error should always be
returned if any attempt is made to lock an already locked config.

Therefore, para. 2 is correct and para. 6 is incorrect.

Can we agree on this interpretation so managers can expect
a consistent API?

thanks,
Andy
