Is it?

I thought Adspec was only optional for the ingress node (or source host
in non-MPLS RSVP), and that routers received a Path without an Adspec
were required to provide one to the next hop.

Do you mean that it's legal for a transit router to emit a Path message
without an Adspec object?  (Assuming it received a Path without one, of
course.)
