Re: [emergency] EDXL Target Areas for device coded recipients

[Art Botterell <acb@incident.com>]

Following on my previous... Kon's specific example refers to groups  
of one or more devices.  That seems like it might be addressed either  
by explicit addressing using <recipientAddress> or a keyword  
reference rather than by using the <targetArea> structure.  After  
all, a device or set of devices only indirectly describes an area...  
a device might be moved without changing its identity.

Of course, there are many situations where we might want to send a  
message to "every device of class X within geospatial area Y" without  
necessarily knowing ahead of time which particular devices fell in  
that class at that time.  That's where <targetArea>, possibly in  
concert with a keyword, would apply.
