Any object that doesn't represent a service-kind-of-thing.

The term "replaceable" is used in the context of acquisition. Making 
things non-replaceable is a way of providing a particular service (say, 
a MailHost), and ensuring that this service will not be inadvertantly 
shadowed by something else (a DMTL Method perhaps) in a higher-up folder.


The concept of "replaceable" isn't needed in Zope 3, as services are 
kept separate from content.
