In conjunction with the annotated
document these notes are clear, except for 'sp165'. Perhaps someone will
recapitulate the discussion briefly at Wednesday's conference. I think
only three annotations remain:
sp167 Absent and
missing (expanded discussion on the wiki already)
This will be a major topic on
a call.
sp172 separatorType="infix"
I'm happy to drop this strange
stuff about separatorType=prefix or postfix and just say separator means
infix. However, I would note that at least two major integration products
(IBM WebSphere Transformation Extender - formerly Mercator, and Microsoft
Biztalk, have this concept, so we may end up putting it back in. Presumably
MS copied the earlier Mercator style, or both got it from common requirements
in some EDI standard.
sp173 defaultWhenMissing
(expanded discussion on the wiki already)
Same topic as sp167 above. Will have a call topic to discuss.
I've added another contribution
to the wiki discussion on 'require'.
This seems to be at resolution
I think, which is that we can express this using assertions. The general
style of using DFDL to describe what fixed-data syntactic constructs look
like is a good one.
However, I've amended the Wiki
thread on this with a further issue for group consideration. See bottom
of page:
https://forge.gridforum.org/sf/wiki/do/viewPage/projects.dfdl-wg/wiki/Require?_message=1187096164776
The 'length and occurs' proposal
is an improvement, though I still have reservations to discuss; likewise
the 'opaque data' proposal.
For a call, this week or soon. I will
send out an agenda.

Subject: [DFDL-WG] Minutes from 2007-08-08 Call
MikeB, Geoff Judd, Alan Powell attended.
Continued through SP's comments.
sp37 - got it.
sp45 - agree. This whole part to be rewritten.
sp115 - ok. strict and "lax" as enums. No built-in default -
we never use defaults in the processor itself. Only in the predefined formats.
sp118 - ok
sp123 - Proposal to simplify length, lengthKind, lengthUnits, and also
occursKind, occursPath, occursPathUnits needed. (along the lines of byteCount,
itemCount, length='delimited' enum, etc.)
sp154 - Need specific proposal to eliminate hexBinary and use what for
opaque (consider also string with encoding='bytes'. ) Or introduce
a dfdl:byteString type or dfdl:opaque type. (derived type - just a standard
name).
sp158 - see sp123
sp165 - needed to have composition property for enclosing groups and or
end-of-data. Regexp doesn't fix this.
