ArrayList, Vector, Collection, List are supported by default.
If you want to manage a Map, you have to specify the attribute
"collectionClassName" in the collection descriptor. There is an
example in jcrmapping-testmappings.xml. The collectionClassName
contains the ManagableCollection implementation to use. See an example
in jcr-mapping/src/test/org/apache/portals/graffito/jcr/testmodel/hashmap

We can see how to support eg. HashMap, Map, ... by creating a default
implementation for the ManageableCollection interface.

See also ManageableCollectionUtil

In summary with the ManageableCollection, it is possible to support
any kind of collection or any kind of Map. The drawback is to write
severals implementations.

		<field-descriptor fieldName="path" path="true" />
		<field-descriptor fieldName="text" jcrName="text" />
		<collection-descriptor fieldName="elements" proxy="false"
