title: Manage @NamedNativeQuery and schema
body: <p>I have many <code>EntityManager</code>, one per schema that I have (I use <code>entity-mappings</code> file to map EMs with schemas). It works.</p>
  
  <p>When I use <code>@NamedQuery</code> it's working like a charm but when I use <code>@NamedNativeQuery</code> schema is not used. I have to qualify with it <code>SELECT foo FROM schema.table</code>.</p>
  
  <p>Is it the right behaviour ?</p>
  
  <p>I think it's not possible to parameter <code>@NamedNativeQuery</code> to dynamically pass schema (I believe only columns can be dynamics not tables or schemas or anything else) so how can I use <code>@NamedNativeQuery</code> with dynamic schema please ?</p>
