/// to test whether the value of a geometric property (referenced using the name
/// of the property) and another geometric value satisfy the spatial
/// relationship implied by the operation. Some feature providers may only
/// support literal geometric values; if so, the provider's capabilities 
/// will indicate this limitation.
