( predicate x y )

Converts X,Y into a point using predicate to find the geospatial mapping.

For example:

prefix geofn: <>
select ?point {
bind(geofn:toPointXY(<http://ex#predicate>, 30.0, 34.0) as ?point )

If either X or Y is outside the range for the mapping, then the point will remain unbound.
