no_cancel_in_alert_or_update

no form of the word "cancel" should appear in the headline, description or instruction of any <info> within an <alert> of any type other than Cancel.

A cancellation belongs in its own <alert> with <msgType> Cancel, so automated handling can act on it as a coded signal rather than prose. Any form of "cancel" appearing in the headline, description or instruction of a non-Cancel message — stated only in text, with nothing coded to signal it — is invisible to automatic alert processors
