#17 <composite-element> not properly synchronized with Generics

Hello,

It clearly seems there is a problem synchronizing the tag <composite-element> as reported in several threads on the Hibernate Synchronizer forum, i.e.

The problem is the "class" attribute of tag <composite-element> is not taken into account, unless you copy/move it to the appropriate collection containing tag (e.g. <set>, <map>, <list>...)

Having something in a class mapped like:

<set name="myElements" table="MY_TABLE" cascade="all">
<key column="MY_ID" />
<composite-element class="MyElement">
<property name="value" column="VALUE" type="long" not-null="true" />
</composite-element>
</set>

generates the following Java code in the corresponding class member:

private java.util.Set<null> myElements;

which is indeed WRONG.

Note that the above mentioned work-around (copying/pasting the class declaration to the <set>) makes the corresponding *.hbm.xml NOT passing the XML Validation, because of the Hibernate DTD not allowing such an attribute ("class") in a <set> declaration.
