[Zope-CMF] Demo types that implement portal_metadata?

[Francis Potter]

Has anyone developed a Content Type that implements the verification and
default-setting capabilities of the metadata tool? It seems like it
shouldn't be too hard to have a mix-in class that implements these
functions. The fact that the default classes don't do it implies that it
might be difficult. If someone has done it, please share. Thanks.

(Otherwise, what's the tool for?)
