@quirk caTissue Bug #147: SpecimenRequirement query ignores CPE.
   Work around this bug by an inverted query on the referenced CPE.

 @quirk caTissue Accessing an annotation hook DE proxy attribute uses a separate mechanism.
   Redirect the query to the annotation integration service in that case.

 @quirk caTissue Bug #169: ContainerPosition occupied container query returns parent
   container instead. Substitute a hard-coded HQL search for this case.
