Hello Paul,

Dups doesn't matter. It's generally not defined for a Collection (see
javadoc of Collection).

>>>>> I think it is useful to allow also Set and SortedSet. Sometimes
>>>>> the order is irrelevant and/or dublicates could or should be
>>>>> ignored for the app. I propose also to allow Collection.
>>> What would be the order and dups policy when Collection is specified?
>>> I don't think Collection should be allowed and the developer should
>>> be explicit about the ordering/dups through the Java type specified.
>> Doesn't matter, that means runtime environment is free to choose. If a
