[sc34wg3] Comments on Part 2

[Martin Bryan]

The following comments apply to the November 2003 draft of Part 2:

5.4.3
Are the words "do not" in the second paragraph correct? I find this strange
with respect to subject identifiers at the very least.

5.4.4
The words "together" and "all" do not conform with the decisions I
understood were made at your last meeting.

5.4.6
Diagram needs to have the same labels as the properties listed in the text.
(Applies elsewhere, but the discrepancy is most noticeable here.)

5.5
In second paragraph you correctly use the word "contexts" in the plural, but
this presumes that 5.4.4 should read "any" rather than "all". If you insist
in retaining "all" then this can only be the singular "context" as only one
context is defined by the complete set of scope identifiers.

5.7
In point number 4 change "the occurrence relationship" to "purpose of the
occurrence". For example, the type could be set to "HTML" or "PDF" to
indicate the format of the occurrence, or to "draft" and "final" to indicate
the state of the occurrence in some applications. Neither of these is
strictly a relationship. (They are both differentiators.)
NB I'd prefer to say "role of the occurrence" but role has a specific
meaning in XTM. However, for occurrences type has the same purpose as role
in associations.

6
In each of the subclauses you should specifically mention the need to remove
A and B after creation of C
