ISCSI: Login Parameters - Defaults?

["LEMAY,KEVIN (A-Roseville,ex1)" <kevin_lemay@agilent.com>]

Page 64 in iSCSI v12 says,
 
 "All negotiations are stateless and explicit (i.e., the result MUST be
based only on newly exchanged values). There is no such thing as implicit
offers. If an explicit offer is not made then a reply cannot be expected."

It is unclear to me how this is supposed to work. Does this mean that I must
negotiate every key pair? This is confusing because chapter 11 still
contains default values.

If I do not negotiate a parameter, is it assumed to be set at the default or
must I negotiate every parameter ?

If I must negotiate every parameter, then the "default" value should be
removed or renamed to "suggested setting".

Thanks,
