Specs should say if the disco reply may be cached, if it may be assumed
to be always up-to-date, etc.
It will be no good special servers with proprietary extension would be
required for good work with mobile client.
When specs would say nothing about that and server would programmer
assume, that it may be cached and implement caching, client programmer
could assume that it never is cached and. eg. reply with different
feature list to different users, then that client and that server whould
not work well together.
