Re: LANG: frame paradigm

I think we should consider the UML class model also as background
reference. 

UML class (various books, incomplete listing of features)
- subclass relation
- disjointness, completeness (through constraints)
- attributes (datatype properties) and relations (object properties)
- cardinality constraints for attributes and relations
- default values for attributes
- class-scoped attributes (same for every member of class)
- part-whole relations between classes (strong=composition,
weak=agrregation)
- abstract vs. concrete class, root and leaf class
- tagging through stereotypes and tags

Guus
