Hi Daryl,
 This is one feature, for a long time, I am interested to be included in JPA
or at least in OpenJPA. Having your queries *only* in the major compilation
unit is a poor idea for usability point of view and takes away much of the
power from tuning a query a posteriori.
  However, I had considered the facility slightly differently than yours.
The primary feature that I considered important in this aspect is to
dissociate my queries from the major compilation units. The compilation
units will only refer them by name. 

 How about the following
  <property name="openjpa.NamedQueryRegistry"
value="path/to/file/that/contains/NamedQueries.java"/>

  and in code
   Query q = em.createQuery("ANameThatAppearsInNamedQueryRegsitry");
