Right. But this needs to be an opt-in kind of feature rather than something
that may happen magically by default. Note that I'm not ruling out the
possibliity that it's a good idea for ExtensibleMetadata to opt-in and allow
modifications to its schema independent of the rest of BaseSchema. I'm just
wary of over-generalising too soon. :)
