Re: [provision] RESEND: Spec issue #14: Declaring the Structure ofComplex Reference Data.

Thanks, Jeff.  I believe that your suggestion will work nicely. 
- Adding an optional <referenceDataType> of type SchemaEntityRefType 
should allow the <referenceDefinition> to point to any element that is 
defined as part of the target schema (as the structure of reference data 
should be). 
- Specifying that a <referenceDefinition> must contain a 
<referenceDataType> for each possible structure of reference data (and 
thus that the absence of any <referenceDataType> means that a reference 
definition does not support reference data) makes this clear and explicit.
