[news.eclipse.modeling.mdt.uml2.uml] EnumerationLiteral is an InstanceSp

[Andreas Maier <maiera@xxxxxxxxxx>]

Kenn,
on 1., I think my question boils down to whether or not I can have 
multiple slots and values on an EnumerationLiteral. There is no 
restriction in the UML 2.1 Superstructure spec that would disallow this 
and I would like to find out whether or not this is a bug in the spec.

An Enumeration is used as a datatype by let's say a property. I could 
well imagine that such a datatype could be of a multi-valued nature, 
i.e. a single EnumerationLiteral has multiple Slots&Values.

On a simpler point: If I look only at single-valued enumerations, which 
UML metaclass attribute or association of EnumerationLiteral represents 
the single value ? The specification association, or an entry in the 
slot (array) association ?
