@ManyToMany and extra fields in link table

After searching this forum, it appears that everyone suggest mapping two @ManyToOne mappings to an Entity object for the link table, but I also know in XML mapping before we could use a composite object instead like

Code:

<class name="Category" table="CATEGORY">

    <set name="items" table="CATEGORY_ITEMS">
      <key column="CATEGORY_ID"/>
      <composite-element class="CategorizedItem">
          <parent name="category"/>
          <many-to-one name="item" class="Item"
                       column="ITEM_ID" not-null="true"/>
          <property name="username" column="USERNAME" not-null="true"/>
          <property name="dateAdded" column="DATE_ADDED" not-null="true"/>
        </composite-element>
    </set>

</class>

Is there an equivalent to that in Annotations, even if it is Hibernate Specific as opposed to JPA.

Thanks
