Super sets attribute
Keywords: super set relation
Defining an extent in an ODABA XML schema, a superSet attribute can be added for defining one or more super sets for the extent. The attribute string has the following syntax:
superSet="superset1 [, supersetN]"
Superset names are extent names separated by comma. In connection with super set definitions the intersect option can be defined.
Notes:
The super set definition implicitly creates subset definitions for the referenced extents, i.e. subsets need not explicitly be defined for the extents referenced as super set.
