It can also happen that a producer administrator decided to change its requirement for registered consumers.

Let's walk through an example using the self producer. Let's assume that registration is requiring a valid value for an email registration property (as we have seen so far). If you go to the configuration screen for this producer, you should see:

Now suppose that the administrator of the producer also requires a value to be provided for a name registration property. We will actually see how to perform this operation in GateIn when we examine how to configure GateIn's producer in Section 6.7, “Configure GateIn's WSRP Producer”.
