iSCSI: RE: How Target knows if Initiator is draft 07 or 08?

[Black_David@emc.com]

Given that the protocol is still under development, the
Initiator should be doing -08 (actually -09 now), and if
the Initiator can't cope, it's broken and needs to be
updated.  I'm not real pleased that the version number
has advanced over the course of draft revisions, and
the final RFC will NOT contain features intended only to
support implementations that use an old draft version
of the protocol and hence don't comply with the RFC.

Every Internet-Draft contains a long version of
"subject to change", and implementations based on old
versions need to be updated as opposed to burdening
implementers who are making the required changes with
the hassle of dealing with other implementations that
haven't.  Be forewarned that further requests of this
form may result in instructions from on high to rev
the version number downward in a future draft version.

Thanks,
--David
