                 Key: HHH-3183
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3183
             Project: Hibernate3
          Issue Type: Improvement
          Components: core
         Environment: Hibernate-3.2.5, HSQL database, Java 1.6.0_01
            Reporter: Nate
            Priority: Trivial


I am unable to define a custom type for a value type of a list.  I have a List<Foo> and a custom CompositeUserType for Foo.  I need to configure Hibernate to use the list with the custom type.  The 3.0 DTD for Hibernate does not have a "type" attribute for the composite-element.  It only permits the properties to be listed of the element like below.

	<list name="foos" table="Foos">
		<key column="Parent_ID"/>
		<list-index column="ListPosition"/>
		<composite-element class="Foo">
			<property name="bar" column="Bar"/>
		</composite-element>
	</list>

What I want is to define a custom type for the composite-element like below.

	<list name="foos" table="Foos">
		<key column="Parent_ID"/>
		<list-index column="ListPosition"/>
		<composite-element class="Foo" type="FooCompositeElement"/>
	</list>

It would also be nice to have an annotation for Embeddable objects to do the same thing.  For example, I can declare an object of type Foo to be Embeddable and also define a custom CompositeUserType for Foo.
