I think the XEP doesn't solve the main problem of cache invalidation
and that's why I think it's pointless and I'm not going to implement it
until the invalidating rules are described. And for those who think
cache polution is a problem can request/store features per JID: there
is absolutely no need to introduce yet another incompatibility just for
a very tiny problem which can be solved in the other way.
