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