DDS15 — No specific package definition for the entities of the model in case of JAVA language binding

The DDS specification document does not prescribes a specific package definition for the entities of the model in case of JAVA language binding; in the IDL only a "DDS" module is defined which does not result in a strictly specified package structure (it might only imply that the entities belong to the DDS package/namespace). It would be useful to have a precise statement indicating at least for the JAVA binding the packages to which the DDS Entities must belong in order to have all implementations using the same packages for the same Entities (e.g org.omg.dds.infrastructure, org.omg.dds.domain, etc..)
