Could you please clarify this sentence from Section 2.16 from the new draft:

"However, the target SHOULD NOT issue overlapping R2T request (i.e.
referring to the same data area)."

It seems to conflict with your statement above.  Or if you interpret them as
not in conflict because of "SHOULD NOT" vs. "MUST NOT", then why isn't it
analogous to say that the target SHOULD NOT overlap an R2T with the implied
R2T corresponding to the unsolicited data?

Thanks,
