Isn't that how it is done now? Are we not just describing namespaces?
The only tricky bit is knowing when to refresh the cache. Most often, in
my line of work, that is a manual decision that is determined by my
choice of time to have my world disrupted by updated definitions.
Free updates of definitions are never really free.
For interoperability, one needs some version control and a way to judge
compatibility (upward is nice). (01)
