<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"

 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.
