Re: [CCAMP] [Last-Call] Last Call: <draft-ietf-ccamp-wson-yang-25.txt> (A YANG Data Model for WSON (Wavelength Switched Optical Networks)) to Proposed Standard

[tom petch <[e-mail]>]

A new verson of this I-D has been posted with substantial changes.  In 
particular, the sequence of definitions in the YANG module has been 
changed while the YANG tree diagram has not been updated to match.  Look 
for example at augments 4, 5, 6 and 7.  In the tree diagram, as in -25, 
they are to label-start, label-end, label-step, label-hop; in the module 
they are to 'from', 'to' and then switch from node attributes to 
information source.

It is technically possible for me to review -26 against -25 but it would 
take so long that I am not going to do it.  My review is to compare, 
side by side, old and new, so resequencing destroys that and with a 62 
page I-D I will not contemplate any other approach.

A new tree diagram, to match the YANG module, again would not make it 
feasible.  The module sequence needs to be the same as in -25 for me.
