Section 5 says:
 
   a key=value in the data part of one of the following Login or Text
   Response or Request.
 
It is plural so should it say "PDUs"?
 
   a key=value in the data part of one of the following Login or Text
   Response or Request PDUs.

DLB> A reasonable editorial clarification request.
 
-----------------------
10.12.4 says:
 
   The version number of the current draft is 0x01. As such, all
   devices MUST carry version 0x01 for both Version-min and Versionmax.
 
Version-min and Version-max are a part of a login request. Is it saying that
an initiator may only use a min of 1 and a max of 1? Or is this saying that
my target can only accept a min of 1 and a max of 1?

DLB> This change to the version number is NOT to be made!

Section 11 says:
 
   Other keys MUST NOT be used.
 
What about these?
   a) Z-reversed.vendor.dns_name.do_something=
   b) Z<#><IANA-registered-string>=
 
DLB> Only when used by an authentication method, as indicated by
DLB> the last item in the list preceding this sentence.  The sentence
DLB> is correct as it stands, and this was intentional, as adding
DLB> arbitrary additional negotiation to the Security phase is a good
DLB> way to introduce security problems.

Section 13 says:
 
   The well-known
   system TCP port number for iSCSI connections assigned by IANA is 860
   and this port can be used with an override.
 
Can someone clue me in as to what an "override" is? Does this simply mean
I should support both 3260 and 860 at my target?

DLB> The wording needs to change to be clearer.  Julian's email said:
DLB>
DLB>     -port numbers (default unchanged but can be
DLB>        overridden with the system port 860)
DLB>
DLB> What this means is that any unadorned reference to "the well-known
DLB> iSCSI port" means port 3260, without exception.  Port 860 is available
DLB> for iSCSI for those who want or need a system port, courtesy of IANA,
but
DLB> in order to use port 860, it MUST be explicitly specified.
Implementations
DLB> MUST NOT default to use of port 860, as 3260 is the only allowed
default.
