Subject: Re: [emergency] Mandatory fields when msgType=Cancel ?
The U/S/C triad is mandatory whenever the optional <info> block is present. In most cases you're right, a Cancel won't have an <info> block at all. However, some senders have expressed a desire to be able to annotate their Cancel messages with new <headline>, <description> etc. elements... e.g., in the case of an all-clear from a hazmat incident. In that case, the U/S/C values should reflect the new, post-crisis situation. (I've never been entirely satisfied with that arrangement myself, but nobody's come up with a simpler one.) - Art At 11:57 AM -0500 1/31/05, Bob Wyman wrote: >In CAP V1.0 and draft V1.1, it appears that <urgency/>, <severity/>, >and <certainty/> are always required fields.
