hi job,

thanks for reading

in my dotage, i try to impress with words less and less

it's why we have references.  but indeed, we have woven a tangled web,
as we saw in the secdir review of draft-ietf-opsawg-finding-geofeeds.
sympathies to the reviewer.  but i doubt we can fix it here.

you really think this make it easier to understand?  but sure,
organizations it now is.

you are not expected to remember bill's bait and sushi.  i assume you
would prefer examples use more erudite names.  sigh.

fyi, bb&s is an iconic internet org similar to foo widget company.  in
this case, bill was bill manning, a friend to many who died recently;
hence the bit of memoriam.  and roberto's taco stand is just up the
road.  i strongly recommend the carne asada burrito.

you are referring to

   Then there is the temporal issue.  The owner of that AS may be BB&S
   today when some document was signed, and could be the Government of
   Elbonia tomorrow.  Or the resource could have been administratively
   moved from one CA to another, likely requiring a change of keys.  If
   so, how does one determine if the signature on the real world
   document is still valid?

are you suggesting automated periodic validation off a cron job or
whatever?

clue or example on how this will help make this document better?
