IMetadataProvider.NotifyMpnDeviceAccess Method

Called by Lightstreamer Kernel to check that a User is enabled to access the specified MPN device.

Take particular precautions when authorizing device access, if possible ensure the user is entitled to the specific platform, device token and application ID.  

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