/** \brief Service abstract base class

* connections a "service network," which is similar to what DirectShow calls
* a filter graph or what gstreamer calls an element pipeline.
*
- * \event \em service-changed
+ * \event \em service-changed a filter was attached or detached or a transition was connected or disconnected
* \event \em property-changed
* \properties \em mlt_type identifies the subclass
+ * \properties \em _mlt_service_hidden a flag that indicates whether to hide the mlt_service
+ * \properties \em mlt_service is the name of the implementation of the service
* \properties \em resource is either the stream identifier or grandchild-class
* \properties \em in when to start, what is started is service-specific
* \properties \em out when to stop
* \properties \em _filter_private Set this on a service to ensure that attached filters are handled privately.
* See modules/core/filter_region.c and modules/core/filter_watermark.c for examples.
- * \properties \em disable Set this on a filter to disable it while keeping it in the object model.
* \properties \em _profile stores the mlt_profile for a service
+ * \properties \em _unique_id is a unique identifier
+ * \properties \em _need_previous_next boolean that instructs producers to get
+ * preceding and following frames inside of \p mlt_service_get_frame
