Weekly Working Group Conference Call

Attendees
Mike Beckerle (Oco)
Steve Hanson (IBM)
Alan Powell (IBM)


1. Go through actions
status updated below

003: AP is updating spec from WTX review and will produce a list of 
remaining unresolved items

007: Discussion about how expressions can be allowed in enumerated fields 
such as encoding. Simplest would be to convert enum properties to string 
but that wouldn't allow schema validation to catch errors.

2. Version 003 work items
The list of work items had been distributed and was discussed. Items 
requiring discussion will be converted to actions. Work items will also be 
tracked in this meeting.

3. Update to Decimal supplement
SH had distributed an updated proposal which was discussed. General 
agreement on the changes with the main point of discussion being the use 
of numberCheckPolicy to control the behaviour of the new numberZeroRep 
property. MB to review

4. Discuss lengthKind issues identified by WTX 
Not discussed

5. Hidden proposal
Not discussed

6. AOB
Agreed an additional weekly  WG call is needed. MB to set up
