IMetadataProvider.NotifyMpnDeviceTokenChange Method

Called by Lightstreamer Kernel to check that a User is enabled to change the token of an MPN device. If the check succeeds, this also notifies the Metadata Adapter that future client requests should be issued by specifying the new device token.  

Take particular precautions when authorizing device token changes, if possible ensure the user is entitled to the new device token.  

Push Notifications is an optional feature, available depending on Edition and License Type.
