>          Issue Type: Improvement
>          Components: structure

> We currently support the following {{Cardinality}} states:
> * {{single}}: one property per property key.
> * {{list}}: any number of properties per property key.
> * {{set}}: multi properties for the property key if and only if the values 
> are unique.
> Right now equality for {{set}} is determined by {{Object.equals}}. This may 
> be sufficient for most users, but maybe not. Next, this is an expensive 
> operation for vendors that don't index on value. Finally, it seems to be of 
> limited use in practice due to its complex behavior regarding meta-property 
> overwriting. I think its best to NOT include {{set}} as an option -- 
> simplifies the API and is more aligned with the core semantics of:
> * {{single}}
> * {{multi}}
