Issue 131: Allow for Collection types

Javadogs,

Currently the spec does not appear to support an element that allows  
mapping a collection (duplicates allowed) to a table with a column  
specifically to allow duplicates. We have an <order> element but it  
seems to be just for ordering.

I'd like to propose using the order element to be used for  
duplicates. As a side effect, the collection might be ordered but  
that's not a requirement. Or should it be?

<spec>
ELEMENT order
This element specifies the mapping for the ordering component of  
arrays and lists.
</spec>

<proposed>
ELEMENT order
This element specifies the mapping for the ordering component of  
arrays and lists, and for the mapping that allows duplicates in a  
collection.
</proposed>
