Re: [Sidrops] I-D Action: draft-ietf-sidrops-rpki-prefixlist-01.txt

[Russ Housley <[e-mail]>]

I am confused by this change in the syntax:

   IPv4Prefixes ::= SEQUENCE (SIZE(1..MAX)) OF AddressPrefix{32}
   IPv6Prefixes ::= SEQUENCE (SIZE(1..MAX)) OF AddressPrefix{128}

   AddressPrefix {INTEGER: len} ::= BIT STRING (SIZE(0..len))

What does it mean when the prefix is a zero length BIT STRING?

Nit: you might want to change le to maxlen to make it clear that it is a bound, not the actual length of the prefix.
