[Zope] Using superclasses from new ZClass

Hi I want to make a i18n-aware ZClass for a product catalogue. I am learning to use Localizer for the i18n. In the tutorial, it explains how to make external products that use the Localizer classes (LocalPropertyManager in particular). Is it possible to do the same using ZClasses? I have made a new ZClass and have used LocalPropoertyManager as a superclass, but I don't know how to use its methods, etc. Felix.
