1.        045  - Disciminators
Continued discussion of semantics of discriminators and arrays. Review Examples

2.        Clarification of postfix separators, terminators,finalTerminatorCanBeMissing
Confirm Proposal:
- Last 'postFix' separator is not optional
- Terminators are mandatory.
- dfdl:documentFinalTerminatorCanBeMissing - the last terminator in the data stream may be missing. Is only examined when processing the root element a global element is a child of xs:schema
- dfdl:documentFinalSeparatorCanBeMissing - the last separator in the data stream may be missing.  Is only examined when processing the root element a global element is a child of xs:schema

3.        Does the parser/serializer have to start on a global element?
-  Confirm
It was agreed that it would be helpful for tooling, importers, etc to know which elements are possible 'root' elements even though XML doesn't have this capability.
A new property, dfdl:documentRoot,  will be defined that can only be on global elements.
The property is optional, it does not prevent the DFDL processor from starting at any other element.
A DFDL processor or tooling may choose to optimise based on this property.

4. LengthKind = 'bits'
Review Mike's draft  

5. Semantics of length=0
Should a field length of 0 , from expression or prefix for example, mean the element is present but length zero or not present?
Should occurrence be used to control existence and length to control length?

6. Go through remaining actions

7. Draft 037 review
Agree terminology

-A schema has components which have dfdl annotations
.- Dfdl annotations have properties (attributes)
-The data/data stream/message has elements/fields
-The infoset has items

8. Plan to finish DFDL v1 Schedule

09/06: Progress but not discussed
17/06: Discussed briefly
24/06: No Progress
01/07: No Progress
15/07: No progress. MB not happy with the way the algorithm is documented, need to find a better way.
29/07: No Progress
05/08: No Progress. Will document behaviour as a set of rules.

16/09: no progress
30/09: AP distributed proposal and others commented. Brief discussion AP to incorporate update and reissue
07/10: Updated proposal was discussed.Comments will be incorporated into the next version.
14/10: Alan to update proposal to include array scenario where minOccurs > 0
21/10: Updated proposal reviewed
28/10: Updated proposal reviewed see minutes
04/11: Discussed semantics of disciminators on arrays. MB to produce examples
11/11: Absorbing action 033 into 045.  Maybe decorated discrminator kinds are needed after all. MB and SF to continue with examples.  
18/11: Went through WTX implementation of example. SF to gather more documentation about WTX discriminator rules.
25/11: Further discussion. Will get more WTX documentation. Need to confirm that no changes need to Resolving Uncertainty doc.
04/11: Further discussion about arrays.
09/12: Reviewed proposed discriminator semantic.

20/05 AP Built-in specification description and schemas
03/06: not discussed
24/06: No Progress
24/06: No Progress (hope to get these from test cases)
15/07: No progress. Once available, the examples in the spec should use the dfdl:defineFormat annotations they provide.
...
14/10: no progress
21/10: Discussed the real need for this being in the specification. It seemed that the main value is it define a schema location for downloading 'known' defaults from the web.
