The object associated with the polygon will usually be inside the polygon,
as the multiline object expresses the coordinates as offsets from the 
object location.  I suppose if the office wanted to they could always center
the object at a standard location, but I expect that they wouldn't.

http://home.earthlink.net/~kg5qd/protocol.html
has details about the multiline protocol, including the intended meanings of
the different colored boundaries.

Lately, though, many NWS offices have been sending out data that has been
misinterpreted by wxsvr and mangled to include illegal characters.  Xastir
spews warnings about this every time they show up.  Recent info on APRSSIG
seems to point to this being due to extra fields being output by the NWS that
aren't parsed by the wxsvr code.    There's been quite a few messages on our
list about those warnings, but no real resolution.  From the sound of it, the 
resolution will have to come from wxsvr.
