> I have added a new GenericSettingDescriptor subclass containing a

> GenericSettingDescriptor >> addStateXmlElementsTo: anElement
> "Subclasses with persistable state must redefine this method to
> store
> their state in the XML element passed as the argument.
> The argument is the <state> child of the <setting> node created
> to represent this setting.
> Subclasses in which #hasPersistableState answers false do not
