Julian,

A few questions/comments..

1) The following suggestion on seems to be missing from 
   the draft
      http://ips.pdl.cs.cmu.edu/mail/msg03273.html

2) There is a WN before the BHS and every AHS.
   So what are the WN bits (6-4) for a BHS ?
   Right now, there is 0=ext_cdb, 1=bidi, 2=longdata.
   All the other values (3-7) seem to be reserved.

3) Section 2.17 R2T - see statement before the fig.
    "outstanding R2T MUST be fulfilled by the initiator
    in the order they were received".
   Is this _within_ a command or connection or session.
   I presume its not within a session.
   Could you please qualify and disambiguate?  

4) In Section 2.5 & Sec 2.6 for TaskMgmt commands the
   RefTaskTag, if reserved, is to be set to zero.
   In other commands (e.g. NOP-OUT), an invalid task tag is
   indicated by 0xffffffff.  How about making it uniform
   throughout as 0xff... (or maybe this is an oversight)
