Subject: Re: [emergency] Circle and Polygon

Correct. And to follow on with what Kohn said, there is no reason that an 
EDXL file has an option(s) for external reference (URI/URL) to the actual 
polygon representation. Then let the application determine whether it needs 
to ingest the complex polygon. For one, I would not like to consider what 
the liability implications are if we do not pass accurate boundary 
information (as accurate as possible) when we do not know what all the end 
applications will be.
