many-to-one id=3D"true" is not picked up by hibernate in orm.xml
--------------------------------------------------------------

                 Key: HHH-5405
                 URL: http://opensource.atlassian.com/projects/hibernate/br=
owse/HHH-5405
             Project: Hibernate Core
          Issue Type: Bug
          Components: metamodel
    Affects Versions: 3.5.2
            Reporter: Rolf Thunbo


When making a composite key referring to a target entity something like the=
 following ORM XML should be defined:

<?xml version=3D"1.0" encoding=3D"UTF-8"?>
<entity-mappings xmlns=3D"http://java.sun.com/xml/ns/persistence/orm"
xmlns:xsi=3D"http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation=3D"http://java.sun.com/xml/ns/persistence/orm http://jav=
a.sun.com/xml/ns/persistence/orm_2_0.xsd"
version=3D"2.0">
<entity class=3D"Subscription">
<table name=3D"SUBSCRIPTION"/>
<id-class class=3D"SubscriptionKey"/>
<attributes>
...
<many-to-one name=3D"owner" id=3D"true">
<join-column name=3D"FK_SUBSCRIBER_CVR"/>
</many-to-one>
</attributes>
</entity>
</entity-mappings>

But for some reason the id attribute is not picked up by Hibernate, and the=
refore it does not interpret the relation as a primary key. A workaround is=
 to add a id tag referring to the same property, but it would be nice of Hi=
bernate would pick up the id attribute on the many-to-one relation.
