It's the correct tag. with it, you define joined table
( on a class level )  and properties which should go
inside, are tagged with join-name param
( mea culpa, I forgot to upload fresh docs on
confluence )

It's all in out test cases:
------------%<----------


/**
 * @author Ryan Ye
 * @hibernate.class table="join_parent_table"
 * @hibernate.join name="testJoin" table="join_table"
 * @hibernate.join-key column="join_key_column"
 */
public class JoinMapping {
	/**
	 * @hibernate.id generator-class="assigned" 
access="property"
     *
	 *our test cases:/
	public Integer getId(){
		return null;
	}
	
	/**
	 * @hibernate.property column="join_property_column"
join-name="testJoin" 
	 */
	public String getJoinProperty(){
		return null;
	}
	
	/**
	 * @hibernate.many-to-one
column="join_foreign_key_column" join-name="testJoin" 
	 */
	public Simple getManyToOne() {
		return null;
	}
}
------------%<----------

will produce:
----------------%<-----------
<hibernate-mapping>
  <class table="join_parent_table"
name="org.xdoclet.plugin.hibernate.pojo.JoinMapping">
    <id access="property" name="id">
      <generator class="assigned"/>
    </id>
    <join table="join_table">
      <key column="join_key_column"/>
      <property name="joinProperty"
column="join_property_column"/>
      <many-to-one column="join_foreign_key_column"
name="manyToOne"/>
    </join>
  </class>
</hibernate-mapping>
----------------%<------------
