<DD>This property defines the geometry to be used for styling.<br>
 The property is optional and if it is absent (null) then the "default"
 geometry property of the feature should be used. Geometry types other
 than inherently point types can be used. The geometryPropertyName is
 the name of a geometry property in the Feature being styled.
 Typically, features only have one geometry so, in general, the need to
 select one is not required. Note: this moves a little away from the SLD
 spec which provides an XPath reference to a Geometry object, but does
 follow it in spirit.
