Statement:
6TiCH use case: Push neighbor info to PCE over CoAP? (CoAP: Constrained Application Protocol [RFC 7252])
Discussion:
The relevant text in the draft is:

      "6TiSCH expects that the PCE commands will be issued directly as CoAP requests or be mapped back and forth into CoAP by a gateway function at the edge of the 6TiSCH network. For instance, it is possible that a mapping entity on the backbone transforms a non-CoAP protocol such as PCEP into the RESTful interfaces that the 6TiSCH devices support. This architecture will be refined to comply with [I-D.finn-detnet-architecture] when the work is
      formalized."

This reads like a requirement, however since an alternative is given to using CoAP (i.e. using a gateway) perhaps this statement just gets removed from the use case? Is there any sense to having DetNet specify CoAP or even reference it at all?
