Comment:

 Not sure I agree. The WKT BNF indicates that the rings of a CurvePolygon
 can be *any* of LineString, CircString or CompoundCurve.
 {{{
 <ring text> ::=
     <linestring text body> |
     <circularstring text representation> |
     <compoundcurve text representation>
 }}}
 In this case, the multi-surface text you've defined has a LineString outer
 ring, why not return that?
