Call UnRegisterProvider to remove a provider from the remote data module's list of available providers. Pass a reference to the provider that should be removed as the Value parameter. When a provider is not registered, it is not returned by the CRDMGetProviderNames method, which can be accessed through the TRemoteDataModule interface. 

To temporarily disable a provider, use the provider's Exported property. Unexported providers are listed by CRDMGetProviderNames but can't be accessed through any TRemoteDataModule method calls. 

Before a registered provider is destroyed, it must be unregistered using the UnRegisterProvider method. Providers that have the remote data module as an Owner are unregistered automatically from their destructors.
