+ * If you are planning on making a new service....
+ * Test it out with an ID in the range from 0xf000 - 0xffff
+ * And Change the ID everytime you make significant changes to the
+ * data structures... 
+ *
+ * eg.
+ * const uint16_t RS_SERVICE_TYPE_DISTRIB_O1  = 0xf110;  // First  Revision.
+ * const uint16_t RS_SERVICE_TYPE_DISTRIB_O2  = 0xf111;  // Second Revision.
+ * const uint16_t RS_SERVICE_TYPE_DISTRIB     = 0xf112;  // Final  Revision.
+ *
+ * This minimises the chances of your new serialisers messing with
+ * other existing, older, or proposed services.
+ *
+ * ONLY MOVE your Id once the service has been finalised.
