Agenda:

1. Reports from TC meeting discussions

   Need abbreviated list of issues.  Sylvia will do this.
   This will be more of an internal change list for the tool.

2. HISC update.

3. Recap current status w.r.t. issues and work to be done (tc, ndr, 
codelist)

   The largest issue is extension/restriction from 1.0.
   Need to decide what is backward compatibility in order to design this.
   2 instances validatad against same schema - not going to happen.
   Must change namespace and prefix if you import schema that doesn't 
have to have prefixes.
   If you then import elements from the old namespace that didn't have 
to have prefix,
     now you have to have prefix.  Because the default namespace in the 
schema has changed.
   However, we don't expect to see mixed namespace in a document -
     don't think this willl be done.  Wait for opinions to come back.
   Want single namespace uri for one version, and make explicit where to 
change this
     to go from one version to another.
   Changing the namespace shouldn't mean you need to change the prefix.
   Does still make things complex, though, if yo uhave multiple schemas 
for a document.
   Really what we need is to have everything that is imported carrying 
the new namespace.
   Can move earlier schemas into new namespace.

   Needa  way of appplying a rule that things should be semantically 
compatible.

4. 1.1  schema generation

   See first stab at a list of changes to schemas.
   http://lists.oasis-open.org/archives/ubl/200503/msg00022.html
   Sylvia will convert this into something specific to tool changes for 
David.

   Can't decide anythnig for sure until modeling happens.
   Need to make sure modeling understands how to model minor version to make
   sure what is done is usable.

   Are ndr's for use within ubl only, or for consumers only?
   us gov wants them and so do others, so it seems like they are for outside
     consumption for derivative work.  Need this clarified.

   Red flag: no one has a clear idea of the ubl versioning policies and 
approach.
   Although we have a lot of knowledge about 1.0 and reuse, ubl promised we
   would not start development work before all issues resolved by tc.
   Otherwise will rehash as in last year.  Need some clarity and 
finalization
   on the versioning issue.


5. Schedule review (see schedule below)

   To make 31 March deadline for schema generataion, can take existing 
models
   and do 3 of 5 changes sent by Stephen; C1, C3, C5 (except 'n', 'j').

   This stage will most likely generate feedback from David.

6. Other business

   None.
