RE: [Pce] I-D ACTION:draft-ietf-pce-pcecp-interarea-reqs-01.txt

Hi all,

This new revision accounts for points discussed in Vancouver and on the list. Here are the main changes:
-Removed all text related to the applicability of PCEs for inter-area path computation. This will be moved to an applicability statement draft to be posted soon.
-Requirements for reoptimization, load balancing, objective functions, metrics, cost recording and re-routing have been moved to the generic ID.
-Added a requirement for area recording in a reply (see section 5.2).
-Added one co-author.
-Some rewordings for the sake of clarity.

Any comment on this new version would be welcome.

Best Regards,

JL et al.
