6. XML 2001 messages to give Jon

We agreed to pass along the following messages:

- Review the charter for our SC and provide NDR portal URL

discuss relationship among the "technical" subcommittees in

particular

. Names of the technical SCs

. Charter text for the technical SCs

. URL for NDR portal

- Review our use cases (if we feel they're developed enough by then)

. Working methodology is to develop rules in response to use cases

. These distinguish UBL project from other XSD-using projects

. Quick list of use cases we're working on

- Give an idea of the breadth we're trying to cover in NDR

. Markup naming

. Modularity, namespaces, versioning

. Customization (additive/subtractive)

. Enumerated lists

. Elements vs. attributes

. Local vs. global elements

. Tip of the iceberg -- just the highest priority -- see draft outline

- Structured customization methodology

. Context = business situation

. Need context-dependent changes in business document structure

. Give an example (add GPS field to address in automotive sector)

. We will provide a machine-readable means for specifying these changes

- Talk about the validator support issue and our software test list

. Chose XSD for development, but have concerns (keep looking at

RELAX NG out of the corner of our eye)

. First and foremost -- no interoperability between validators!

. Concerns about restriction support

. Concerns about namespace support

ACTION: Eve to send final notes to Jon and the SC by Thursday.

7. Finish going through the NDR document outline and assign more champions

Mark and Eve took notes on all changes agreed to by the SC.

ACTION: Everyone to review the NDR document and send all comments to

Mark by Friday COB.

ACTION: Mark to turn around a new draft by early next week.

NEW TERM:

Assembly: Using parts of the library of reusable UBL components to

create a new kind of business document type.

8. Legal issues (following on to Arofan's posting)
9. Use case review (Maryann Richards)
10. Tag structure position
11. Customization position
