It appears that this is already possible:

Data =
       element nmwg:data {
               (
                       Identifier &
                       MetadataIdentifierRef? &
                       (
                               Metadata* |
                               (
                                       commonTime+ & 
                                       Datum*
                               ) |
                               Datum* |
                               Key*
                       )
               ),
               anyElement*


       }



The only requirement is the id element, everything else is an optional 
attribute/element so I don't believe we need to change anything.
