Existing Versions

• Two versions, old and new
• Old
• Single W3C XML-Schema
• has some prototype implementations
• New henceforth, the schema
• Modularized, RELAX-NG
• No implementations yet
• Note generated XML-Schemas tricky for current
  tooling

  batches
• Each result section indicates
• Batch

To-Do Before Hawaii

• Finish version 2
• Match requirements
• Reconcile with Request schema
• Test
• May require some hand-translation of RELAX-NG ?
  XML-Schema for existing Java, Perl, and Python
  tooling
• Iterate..
