Hi Editors, authors. 

During discussion on draft-ietf-pce-gmpls-pcep-extensions and other discussion one point that was raised is the fact that the SWITCH-LAYER does require the presence of the INTER-LAYER, but not the REQ-ADAPT.

>From an implementer point of view it would be interesting to specify which layer to use but not have to support the full semantic of the INTER-LAYER object. 
I do think its possible to have the INTER-LAYER always optional. When its not present its considered as a mono-layer request (also for the SWITCH-LAYER).

Do you see any problem with this approach, if no do you think this can be included in the document?

Please find a proposal in the attached document, modified lines start with a '*', 
I also did put some other comments, especially regarding the ERO object.
