/** Basic implementation for a CMIS Set request.

  * This class mainly implements the <code>{@link fr.dyade.cmis.api.operation.SetRequest}</code> interface.
  * It has the filtering and scoping features so
  * it is a subclass of <code>{@link FilteredAndScopedOperationImpl}</code>.
  *
  * Because of java scope properties this class is public, but user can not directly build instances
  * as it is an abstract class. Instances are to be built using
  * {@link fr.dyade.cmis.api.CMISManagerStack#newSetRequest factory method}.
