If the list would be longer than can be accommodated in a single IPFIX
message, then some mechanism would need to be defined to allow the list
to be exported.
Ideally this should be a generic mechanism allowing the export of any
large IPFIX content. However, it might be simpler to define a mechanism
that's specific to the export of long lists.
There may be several solutions. eg, it might be a compression mechanism
allowing the content to fit into a single message. Or the content might
be carried across multiple messages.
If you feel it's an issue - especially if it would block your current
work - then please start the discussion in the OPSAWG because the IPFIX
WG is closed.

The length of IPFIX message is sufficient for BGP standard
communities, since the length of standard community is 4 octets. But
the sizes of extended community, large community and wide community
are bigger than the size of standard community. If the working group
agrees to cover the above all kinds of communities in this draft, do
you think we should open the discussion for IPFIX and basicList
