I reviewed this from a GenArt perspective (a reader new to the area) and have
one request : that early in the document a few sentences be added (copied from
another text) clarifying the difference between stateless and stateful PCE.

This document is otherwise ready to pass to the RFC Editor team.

I note that id-nits picks up a number of errors regarding references (RFC 2119
language and technical references), but the ones I checked seem correct, so I
am not sure what is happening.

Major issues: None

Minor issues: The absence of an early description of stateful PCE as noted

Nits/editorial comments:

   Further discussion of concept of a stateful PCE can be found in
SB> of the concept

   For passive stateful PCEs, Path Computation Request (PCReq)/ Path
   Computation Reply (PCRep) messages are used to request for path
SB> grammar problem
