Here is the first draft of a schema definition for statistical data
destined for the statistical model.  Included is a schema file, HTML
documentation, and a sample instance that conforms to the schema.   I am
looking forward to some feedback.   I will schedual a meeting for Monday
with the previously identified participants to push this forward.

complex type DescriptorType

Documentation

This is the base type for all descriptors. DescriptorType's do not have associated counters but rather provide containment structure so that descriptors have a hierarchy.

complex type DescriptorMember

Documentation

A DescriptorMember is a descriptor that has a counter associated with it. DescriptorMembers are refered to be Observations. DescriptorMember's contain representation information for the observation information they describe.
