XML example errors in section 6 of the manual

I've notice some error in the XML example of the Doctrine ORM manual, section 6.

There is often:
<join-column="user_id" referenced-column-name="id" />
The correct tag should be:
<join-column name="user_id" referenced-column-name="id" />

Also, in the many-to-many bidirectional example is missing the targer-entity tag:
<many-to-many field="groups" inversed-by="users">
Should be:
<many-to-many field="groups" target-entity="Group" inversed-by="users">

I also think that the differents values could be better explained.

Hope this will help...
