1. The first problem of previous model was the ambiguous result of IProperty.getValue() method because IProperty could contain a list of values. If we added new CollectionAttribute we would remove this ambiguity. As a result we would define exactly whether Attribute contains a single value or a list of values.
 
2. The probem with having a multi-valued complex attribute is on higgins owl schema level. It was discussed here:

I'm breaking some of these topics into their own threads.

So we will have exactly one value for SimpleAttribute and for ComplexAttribute, and resolve a problem with ComplexAttribute that now unable to have more than one complex value.
 
 
This is the second time I've heard this assertion.  As far as I know, there is nothing that prevents us from having a multi-valued complex attribute. IAttribute extends IProperty which has a getValues() method.  This returns one or more IPropertyValues.  For a complex attribute, each IPropertyValue will be an IComplexValue.  Let me know if there is something wrong with my understanding.
