The two filters that use the distance buffer type are Beyond and DWithin. </p> <p> From the spec: The spatial operators DWithin and Beyond test whether the value of a geometric property is within or beyond a specified distance of the specified literal geometric value. Distance values are expressed using the Distance element. </p> <p> For now this code does not take into account the units of distance, we will assume that the filter units are the same as the geometry being filtered, and that they are cartesian. </p> <p></p><P><P><DL><DT><B>Author:</B></DT> <DD>Chris Holmes, TOPP</DD><DT><B>Module:</B></DT><DD><CODE><B>module/main</B></CODE> (<A
