I think that attention messages should not be sent with a <body/>,

should be a standalone message of type='headline', like so:

<attention xmlns='http://www.xmpp.org/extensions/
xep-0224.html#ns'/>
</message>
This message looks like <iq/> but <iq/> is better because the
recipient may receive result in case of accepted attention or error in
case of ignored one. The ability of getting a response even makes
disco#info queries unnecessary.
I chose to use <message/> instead of <iq/> because you don't have to
specify a resource to send the message, and you don't need a reply on
this one (every <iq/>-message is a potential memory leak, when the
receiving client doesn't behave properly), because even when the
client displays the attention grabbing event, you can't know if the
user has seen/heard it. Is there a serious reason to go to <iq/>?
The <body/> element is not required in this spec, but I could change
it to SHOULD NOT contain, would that be better?
