Are you talking about the same separation as Christophe did, create a 
ICourseDetail in addition to ICourse. That do not change the way the 
configuration is done, or does it?

Like this then?

    <class class=".course.Course">
        <implements
            interface=".interfaces.ICourse
                       zope.annotation.interfaces.IAttributeAnnotatable"
            />
        <require
            permission="zope.View"
            interface="zope.app.container.interfaces.IReadContainer"
            attributes="shortDesc"
            />
        <require
            permission="zope.ManageContent"
            interface="zope.app.container.interfaces.IWriteContainer"
            set_attributes="shortDesc"
            />
    </class>
