That's not extension. I was expecting a generic way to access and
modify descriptor properties. The "extensions" you are talking about
are going to be completely independents modules that directly
manipulate xobjects and they will have to provide their own complete
API, do there own caching of descriptors etc, extending Wiki class is
pretty useless for them.
