Make an external method: "hasattr_itself" with the following content:

def hasattr_itself(object,attribute): '''return true iff *object* itself has attribute *attribute*.''' base= getattr(object,'aq_base',object) return hasattr(base,attribute)

Put a feature request into the Collector. Zope should provide such a function as a built-in.
