If the order is an integer the <list> mapping is the right way.For some
special stuff you can use <map> to a field and expose something else than a
IDictionary.
If what you need is a sorted ISet, IDictionary by a specific
entity-property, even using a custom comparer, you can use the "sort"
attribute or the "sort" and "collectio-type" attributes.
