> {{ModifiableMetadata}} selects the appropriate collection type for a given element type
by invoking the protected {{collectionType(Class)}} method. Current implementation returns
only {{List.class}} or {{Set.class}}. Consequently {{HashSet}} is used for all {{Enum}} and
{{CodeList}} collections.
> The {{EnumSet}} and {{CodeListSet}} are more efficient (more compact and presumed faster)
implementations of {{Set}} for enumerations and code lists, so they should be used. Note that
since {{EnumSet}} is mutable, we will need to clone it before to return such set from a unmodifiable
metadata.
> We could also move {{collectionType(Class)}} method from {{ModifiableMetadata}} to {{StandardMetadata}}
instead, in order to control the collection type policy in a single place instead than for
each metadata object.
