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.
