RE: iSCSI: not offering a key

["Fischer, Michael" <Michael_Fischer@adaptec.com>]

My question is that if there is no such thing as an implicit value, then a
"default value" shouldn't exist, right?  Isn't a "default" implicit?  

What I am reading from this discussion is that all iSCSI initiators must
send _all_ keys.  How else is behavior going to be stable?

It seems strange to complexify the algorithms on the grounds that
people will implement things incorrectly, but it looks like I'm
fighting a lost cause here so I'll stop now.
