+CM Handle search with CPS Path
+------------------------------
+
+The *cmHandleWithCpsPath* condition allows any data of the CM Handle to be queried as long as it is accessible by CPS path. CPS path is described in detail in :doc:`cps-path`. For this endpoint, the ancestor axis for CM Handles is appended automatically so that a CM Handle is always returned. For example ``/dmi-registry/cm-handles[@module-set-tag='']`` will become ``/dmi-registry/cm-handles[@module-set-tag='']/ancestor::cm-handles``.
