	I have some comments on draft-ietf-ccamp-rwa-info. Most are strictly
editorial. Note that I'm the document shepherd, see RFC 4858 for more

- Please address my general comments on the WSON document set

- You say: " relatively static on the time scales of
   connection establishment."  I suspect you mean:
   " relatively static and independent of connection establishment."

- Your references to [Switch] seem almost normative in nature. I suspect
that this is not your intent as it is listed as an informative
reference.  Please revisit your references and ensure that the draft
does not depend on any informative references.  (Either change the text,
or move the reference to normative.)

- s/inputinput/input

- s/outputoutput/output

- Section 4.1: " ...  and path computation [Encode]."
  While a normative reference to [Encode] is certainly just fine, I
  reference is unclear in this context.

- Why say "potentially switched" vs just "switched"?  if "potentially"
doesn't add anything please drop it, otherwise please clarify.

- Section 4.2: SRNG
  I don't see SRNG in any other documents.  Am I missing it, is SRNG
used anywhere?

- Section 5: I found it hard to parse the following:
   As resources are the smallest identifiable unit of
   processing resource, one can group together resources into blocks if
   they have similar characteristics relevant to the optical system
   being modeled, e.g., processing properties, accessibility, etc.
  Do you perhaps mean?
   A resource is the smallest identifiable unit of
   allocation. One can group together resources into blocks if
   they have similar characteristics relevant to the optical system
   being modeled, e.g., processing properties, accessibility, etc.

-Section 5.1: States: " Note that except for <ResourcePoolState>
  all the other components of <ResourcePool> are relatively static."
  But the related definitions are:

   <ResourcePool> ::= <ResourceBlockInfo>...
   [<ResourceAccessibility>...] [<ResourceWaveConstraints>...]
   [<RBPoolState>] (section 5)

   <DynamicNodeInfo> ::=  <NodeID> [<ResourcePoolState>] (section 7.2)

   What's the intent here?

- Section 5.2: What is the asterisk "*" all about.

- Section 5.3.3 says
   should <client-signal-list> be <ClientSignalList> as defined in
   section 5.2?

- Section 5.3.4 repeats section 5.2.  replace:
  " as follows:

     <ProcessingCapabilities> ::= [<NumResources>]
     [<RegenerationCapabilities>] [<FaultPerfMon>] [<VendorSpecific>]"
  with "."

- Section 6.5: I found the following language confused:
   This allows for the
   definition of one additional link metric value for traffic
   engineering separate from the IP link state routing protocols link
  How about:
   This allows for the
   identification of a data channel link metric value for traffic
   engineering that is separate from the metric used for
   path cost computation of the control plane.

- Section 6.6: Drop "(Wavelength)" from the title, this can be confused
with the "WSON" indication in section headings

- Section 6.6.: You just say (Wavelength) and leave it to the reader to
infer the relationship between it and a label. I suggest you make the
relationship explicit.

- Section 6.6.  I think you have a BNF problem here.  The BNF says
restriction parameters are always optional, but your text says that
there are requirements based on <RestrictionTypes>.  I think the BNF
needs to be aligned with the text and reflect the requirements.

- Section 7: You say " An example usage of this
   information in a WSON setting is given in [Shared]."

  References to URLs should be avoided (particularity when they aren't
  valid even at the time of publication, i.e., now).

That's it on this one,
