i do not think this document is at all ready for publication.  someone
with time and energy to clean up the wording needs to spend a half day
with the poor thing.

---

1.2 i believe that redefining AS and ASN are ill-advised.  just refer
elsewhere.  we readlly do not want to go there.  e.g. there are a lot of
ASs which are not under a single administrative control.

if you insist on defining it, i would probably s/route/as-path/

Aggregate Route makes an assumption that 'more general' and 'specific'
are well definined.  maybe try something like shorter and longer
netmask, or greater or smaller prefix mask length.

'Covering Aggregate' uses 'cover' in its definition, which makes it
pretty useless.

'Multi-homed prefix' is 'originated via'.  is it transited via/through
or originated by/from?

...

   3.1.  Single Announcement

   An organization (Org A with ASN 64496) has been allocated the prefix
   192.168.2.0/24.  It wishes to announce the /24 prefix from ASN 64496
   such that relying parties interpret the route as intended.

look at rfc 5737 IPv4 Address Blocks Reserved for Documentation

i could go on and on.  essentially this document is sloppy and needs to
be seriously cleaned up.
