I was unaware of this work in Manet, and thank you for making an interesting
and useful specification. I have two concerns I’d like to discuss:

1. The text says: “In the absence of a wildcard, a packet may not match any of
the data items and, in this case, SHOULD be dropped by the router.”.- Why is
this not a MUST? (If it needs to be a SHOULD, then please add text to explain
what happens whene there is no match and explain whether sending this pacekt
also consumens credit.)

2. If a packet is not matched and is dropped, ought it to be logged? (It would
be logged if there was no FID). Either way, the specification ought to explain
whether an entry in the log is to be expected.

I don’t think the security mechanisms are sufficiently defined to be useful.
Please can you explain what threats these updates are expected to counter. This
currently leads to two very ineffective security considerations:
