NHibernate Mapping - <list/>

I am not going to talk about all the options that NHibernate has for collections, I already did it for &lt;set/&gt;, and most of that are pretty similar. Instead, I am going to show just the unique stuff about NHibernate’s &lt;list//&gt;. While &lt;set/&gt; is an unordered collection, of unique elements, a &lt;list/&gt; is a collection of elements where the order matter, and duplicate elements are allowed (because there is a difference between item A in index 0 and index 4).
