I strongly agree with Len. Perhaps a good compromise is to add explicit
(attribute)
information that indicates the spatial reference system used by the
element, and that it is the external edge?
Eg <polygonExt srsName="urn:ogc:def:crs:OGC:1.3:CRS84"> 22, -22 ....
</polygonExt>
In our case, we can state that the attribute is mandatory and fixed.
