This draft provides the Yang model for PCEP.

The Yang model should include all PCEP related extensions and which from reading the draft I see missing some major components that should be included detailed in this review.  

Minor issues:

Normative and / or Informative References to the following drafts should be included as well as I see are missing in the PCEP Yang model itself:
