privileged entity xep update: - the xep is now for any entity, not only components - updated according to standard@ feedbacks: - <privileged/> element removed - permissions are also managed in admin mode - in permission form, it is now recommended to use namespaces for 'var' attribute - filled the missing required parts - "privileged" and "managed" entity are now the terms used - if client can't revoke permissions by itself, they must be revoked on disconnection - renamed "xmlns" attribute of <perm/> to "namespace" - server must notify privileged entity if permissions change during session - various typos fixes
