1 Proposal for change to VOTable schema Without changing set of valid documents (modulo undesired ones)

2 Motivation Reuse of certain, but not all constructs (FIELD) Validates easier ( currently valid) OO motivation (see dm session) Similar change accepted in registry group, hopefully in dm. Cleaner design (simpler, example XMLBeans)

4 Changes No element ref construct. No global elements for attributes and contained classes. Analogy to Java binding : –Complex type class –Typed declarations Fields in class definition –Default document a main method using the classes. –Global elements variable declarations local to main method Single inheritance mapping, only extension, no substitutionGroup Requires xsi:type construct to indicate which precise class is used. Can support a more involved special purpose document to/from the official default registry document using XSLT scripts for example (view concept).
