Dear Kingsley, I imagine that Peter is referring to
Req 10 All RDFS Literals of type geo:wktLiteral shall consist of an optional URI identifying the coordinate reference system followed by Simple Features Well Known Text (WKT) describing a geometric value. Valid geo:wktLiterals are formed by concatenating a valid, absolute URI as defined in [RFC 2396], one or more spaces (Unicode U+0020 character) as a separator, and a WKT string as defined in Simple Features [ISO 19125-1]. From page vii of the GeoSPARQL standard. However, I can imagine that you have few customers demanding GeoSPARQL support for Mars at this time ;) So it is just a feature not yet implemented...
