1. Moving to XSD 1.1 as base for DFDL
Went through MB email of 12/11/08 [DFDL-WG] XML Schema 1.1 implications
for DFDL
Agreed the following warranted further investigation
- open content
- Wildcard Element Name Namespace Flexibility - needs clarification of
use in dfdl
- Xsd:all groups - as a replacement for unordered groups
- XPath Usage
- Type Tables and Alternative Conditional Types
- xsd:override
- support primitive datatypes and facets beyond those defined in [XML
Schema: Datatypes]
5. Action Items/ Work Items.
Didn't go through actions.
Agree a new version of the spec would be issuesd at the end of November
and all included work items would be highlighted in work item table
