<very definitely speaking as an individual and not to be taken in any way as AD input!> When we defined the LSP attribute object, we deliberately did not include this function. Our thinking was that we were defining attributes of the LSP and that this function is defining behavior of specific nodes. Attributes of an LSP can be classed as behavior of *all* nodes on the LSP, or behavior of the end points of the LSP. The two example use cases supplied by Mach in his email (http://tools.ietf.org/html/draft-dong-ccamp-rsvp-te-mpls-tp-li-lb-05 and http://tools.ietf.org/html/draft-dong-ccamp-rsvp-te-plr-designation-00) are helpful for understanding the intention of the work, but seem to support my understanding of the purpose. If the authors have a different intention (i.e., not targeting instructions at a specific node on the LSP) then it would be helpful if they spoke up. Otherwise (and assuming that this function is actually needed!) I think it would be helpful to reclass this as a normal subobject of a normal ERO. This would allow the ERO to pass through nodes that do not support the new subobject without having to define a new top-level object that will not be understood and without complicating the ERO processing further. Obviously, returning the fact that the new subobject was processed will require a new RRO subobject. I do not much care whether this change is made before or after adoption as a WG draft, but I do believe it should be discussed at some point, and my current view is that the change should be made at some point. I think adoption probably hinges on whether the WG believes that there is a need to target commands at specific nodes on the LSP.
