[Zope] aq_acquire?

What does an object need to inherit to make aq_acquire work? I've got an object that inherits from Acquisition.Implicit, but whenever something tries to call aq_acquire on it, it cops an AttributeError. Does it need to inherit from Acquisition.Explicit? Why would something be calling this if it's not there automagically? -- Benno Rice "No, no.
