Configuring IIS Security in 4.0

The EvB IIS security page contains the following example:

<? xml version="1.0" encoding="utf-8" ?>
<ConnectEngine>
    <roleAuthorizations>
        <roleAuthorization role="Unify.Event.Service.Read">
            <anonymous action="Allow" />
        </roleAuthorization>
        <roleAuthorization role="Unify.Event.User">
            <group action="Allow" groupName="Users"/>
        <roleAuthorization>
        <roleAuthorization role="Unify.Event.Administrator">
            <user action="Allow" userName="ExampleAdministrator_01" />
        </roleAuthorization>
        <roleAuthorization role="Unify.Event.Agents.Write">
            <user action="Deny" userName="UserWithDeniedAccess_03" />
        </roleAuthorization>
    </roleAuthorizations>
</ConnectEngine>

However, the Unify.Product.EventBroker.EventBrokerPlugInKey.extensibility.config.xml file contains:

<?xml version="1.0" encoding="utf-8" ?> <EventEngine changeId="{025F5A02-200E-4BA3-B74F-72623FAD3731}" />

Has the XML structure changed in 4.0?
