Event-based filtering for subscription service

When registering as a client for the subscription service, a registration form allows selecting following events to subscribe to: a) SAA.ACT, b) SAA.NEW, c) AD.CLS, d)AD.LIM, e)RWY.CLS, f)RWY.LIM, g)SFC.CON, h)OBS.NEW. For every scenario, there is also a possibility to subscribe to the full context event scenario. This means, that the filter reacts on BASELINEs of dnotam:Event time slices. The AIXM 5.1 data and digitalNOTAM are returned together with the referencing time slice, which contains the actual feature change (TEMPDELTA or PERMDELTA) and the underlying BASELINE of the feature change. This will allow clients to receive the full scope of the DNOTAM.
