One or many data models?

["Darran Rolls" <Darran.Rolls@waveset.com>]

As discussed, the committee has to decide on the data model for the 2.0 specification.  On the one hand, as prototyped by Jeff Bohren at the last F2F meeting, we can devise a solution that keeps the 1.0 DSML data model by adding an extensible schema "root" that allowed for its coexistence with a new "XML Schema" data model.  The "cost" of this model is increased complexity.  On the other hand we can take a single data model solution as proposed by Gerry Woods at the F2F and base 2.0 on a pure XML Schema data model at the "expense" of 1.0/ 2.0 compatibility and backwards support for 1.0 in a 2.0 compliant service.

Please consider this issue and ask questions/state preferences now.  I propose we hold a ballot on this issue around the next committee con-call 3/16/04.

Thanks
