Subject: [Spud] SPUD/PLUS Integrity

In draft-trammell-spud-req-04,
Section "6.3 Integrity" says,

"Endpoints should be able to detect changes to headers SPUD uses for
   its own signaling..."

It does not (in this section, at least) say that elements on the path should be able to detect changes to the headers.
Is this omission accidental or intentional?

Section 1.1.1 in the spud-use-cases document does indicate there may be some situations in which there could be such verifiability.

There are a few charging-related use-cases that would be assisted by confirming that a sender has the authority to say what it said.

I can also imagine how DDoS scrubbing might be assisted by examining some integrity aspect of the PLUS/SPUD layer.
