This is all way too complicated. If your client supports the feature (either for all or only a few contacts), advertise it in caps. If it chooses to ignore 'attention' stanzas from certain contacts, then it can do so client-side. This is true for any capability (e.g. i may not want xhtml information for contacts that use a certain client known to send ugly html, ...) cheers, Remko
