11.6 Omitting Zone Indices

11.6 Omitting Zone Indices

The format defined in this document does not intend to invalidate the original format for non-global addresses; that is, the format without the zone index portion. As described in Section 6, in some common cases with the notion of the default zone index, there can be no ambiguity about scope zones. In such an environment, the implementation can omit the %<zone_id> part. As a result, it can act as though it did not support the extended format at all.
