Here are some comments on FCP-2 Revision 02

1.	Clause 3.1 definitions: Add the terms "Recovery Abort" defined in
clause 8.1.2.2, page 37 and "Ambiguous Exchange" defined in clause 8.1.1.4,
page 35. Both of these terms are used in the text before they are formally
defined.
2.	Clause 3.1.16 fully qualified exchange identifer: include reference
to clause 5.1 page 14 where it is fully defined.
3.	Clause 4.1, three references to ANSI X3.270 (SAM). Should these
references be updated to SAM and SAM-2 or just SAM-2.
4.	Clause 4.6, page 10, last sentence: "table 2", should be "Table 2"
5.	Clause 4.9, page 13, last sentence: "Implicit PRLI/PRLO parameters
may be defined for FCP_Ports." Since this technique is not defined here
should a sentence be added to state that this is beyond the scope of this
document?
6.	Clause 6.2.6.5 and 6.2.6.6, page 24: Reader might assume that annex
A is part of ANSI X3.230. Clarify text to state "annex A in this document".
7.	Clause 6.2.6.9, page 24, third line: Cut and paste error? "FCP_DATA
IUs that are move data".
8.	Clause 6.2.6.10, page 24, last line: missing period at end of
paragraph.
9.	Clause 11.1.2, page 57  in "The Exchange responder (SCSI Target)....
list line "4) a Sequence error is detected in an inbound Sequence" should be
an outbound sequence. (The target receives only outbound sequences.)
10.	Clause 11.2.7 FCP_CONF Recovery: This clause should clearly state
that in the case of a lost FCP_CONF, that the Class 3 target is required to
initiate recovery action. This is different than in the cases described in
clause 11.2.5 FCP_DATA Recovery - Write and 11.2.9 Additional error
detection by SCSI Target where the text explicitly states that the class 3
target does not initiate error recovery.
11.	Annex A.4, page 69: Service response description has a formatting
problem. At least it is missing a square bracket.
12.	Annex C, page 77: The tables are labeled with "A" instead of "C".
Table A.1 has the arrow pointing in the wrong direction on "I3 FCP_DATA".
13.	Annex D, page 87: The figures are labeled with a "C" instead of a
"D".
14.	Annex D, page 95, "Figure C.9 - Lost Read Data, Last Frame of
Sequence" The Class 3 Error detection drawing has the REC and ACC arrows in
the wrong direction.
