Code Inspection: Multiple nullable attributes usage

NotNull and CanBeNull attributes can be used to indicate whether or not a parameter or a return value can be null. But consider the following code:

public void SetName([CanBeNull][NotNull]string name) { myName = name; }
Public Sub SetName(<CanBeNull> <NotNull> name As String) myName = name End Sub

This annotation does not make much sense since the two assertions contradict each other.
