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.
