Comprehensibility comments from Gen-ART reviewer:

Document: draft-ietf-mpls-rsvpte-attributes-04.txt
Review: John Loughney
Date: 2 mars 2005
Additionally, I had a lot of trouble actually parsing much of the document,
I am not going to site every single instance, but some examples are listed
below.  I think an editorial pass is needed to enhance the comprehensibility
of the text.

Minor comments
1) Way too much acronyms in the abstract ...
2) Took me several reads to be able to parse the following text:

    .... Because of the nature of the TLV
    construction the object is flexible and allows the future definition
    - further bit flags if further, distinct uses are discovered
    - arbitrary options and attributes parameters carried as individual


    The new RSVP-TE message object is quite flexible, due to the use of the
    TLV format and allows:
    - future specification of bit flags
    - additional options and atttribute paramerters carried in TLV format.

"if further, distinct uses are discovered" and "arbitrary options and
attributes" sounds like an open invitation for folks to invent new things
without good reason ...

3) This text was confusing:

4.2 Generic Processing Rules for Path Messages

  An LSR that does not support this object will pass it on unaltered
  because of the C-Num.


4.2 Generic Processing Rules for Path Messages

  An LSR that does not support this object is required to pass it on unaltered,
  as the C-Num indicates that the LSR should pass the object on transparently.

  Section 1.1 says:
  > The RSVP-TE signaling protocol also forms the basis of a signaling
  > protocol for Generalized MPLS (GMPLS) as described in [RFC3471] and
  > [RFC3473]. The extensions described in this document are intended to
  > be equally applicable to MPLS and GMPLS.
  I would like to see the title and abstract reflect this situation.
