[RTG-DIR]Re: RtgDir Last Call review: draft-ietf-pals-ple

["Andrew G. Malis" <[e-mail]>]

Tal,

Thank you very much for the review!

Authors,

Please respond to the points in the review (copying the working group) and
once you and Tal have agreement on what the updates should be, update your
draft. Once the draft has been updated, I will end the WG last call and
start the publication process.

Thanks,
Andy
