Good point, I have changed this to:

    The software at the ingress node MUST detect this, and MUST have a 
way of alerting the operator that the deployment is not properly configured.

The clarifications and extensions may affect the procedures for 
originating and receiving/processing S-PMSI A-D routes and Leaf A-D 
routes.  These procedures are discussed in many different places in the 
updated drafts.  I don't believe there is any value in having the 
authors of mvpn-expl-track go through those drafts to try to make a list 
of all the places where S-PMSI A-D routes and/or Leaf A-D routes are 
discussed.  If we attempted to do so, we'd surely miss a few places and 
thereby introduce bugs into the spec.  The information currently in the 
document is sufficient to enable anyone who understands the updated 
references to figure out what needs to be done.
