Remove the Slot Class

The concept of 'Slot' in a CCD is left over from the openEHR roots. In openEHR it is required because you must be able to reuse previously approved components. In MLHIM, it is easy to copy a segment of a CCD, that seems to meet your needs, directly into another CCD. This is done during the modelling phase, prior to geneartion of the CCD proper (XML Schema). This is a much cleaner approach and allows for a consistent structure for any given CCD and its instance data.
