AML to add project

Can you help me with minimal AML needed to open a new Project ? I tryed with this one, but it looks I can't handle WBS in a proper way. Probably it should be entered/created as dependency.

<AML>

  <Item type="Project" action="add">

   <name>Test</name>

   <date_start_sched>2014-01-01</date_start_sched>

   <date_due_sched>2014-06-01</date_due_sched>

    <wbs_id>Item type="Test"</wbs_id>       

  </Item>

</AML>
