Sure, this is probably my problem. What would this look like with
ZCML? I have this:
Do I need to, in my .py file, define something =
factory(GeoCodedLocation) and refer to that? This registration felt
wrong, but I couldn't find an example.

sure, or I could just adapt IAnnotations and set anno['geocode'], but
it seems unwise to choose a long-standing design based on something I
just couldn't figure out one day. :)
