Re: [Idr] Barry Leiba's No Objection on draft-ietf-idr-flow-spec-v6-18: (with COMMENT)

Susan, Barry, IDR

I uploaded the -19 that includes the cleanup as discussed:

Section 3.1., paragraph 7:
OLD:

    In the case Length minus Offset is 0 every address matches.  Length
    MUST always be in the range 0-128 and Length minus Offset MUST always
    be 0 or more, otherwise this component is malformed.

NEW:

    Length = Offset = 0 matches every address, otherwise Length MUST be
    in the range Offset < Length < 129 or the component is malformed.

I hope this is clear. Maybe still some minor rewording is needed.

Cheers Christoph

If not, it seems less prone to error to say that length=offset=0 matches every address, and otherwise length MUST be greater than offset or the component is malformed.
