+ * This extension provides for the addition of markers to the either end
+ * or the middle of a line, polyline, path, polygon.
+ *
+ * Markers may be either a graphic or arbitary text
+ *
+ * to simplify the coding and make the implementation as robust as possible,
+ * markers are not shared - every object has its own set of markers.
+ * this relationship is maintained by a naming convention between the
+ * ids of the markers and the ids of the object
+ *
+ * The following restrictions exist for simplicty of use and programming
+ *    objects and their markers to have the same color
+ *    marker size is fixed
+ *    text marker font, size, and attributes are fixed
+ *    an application specific attribute - se_type - is added to each marker element
+ *        to store the type of marker
+ *
+ * @todo
+ *    remove some of the restrictions above
+ *    add option for keeping text aligned to horizontal
+ *    add support for dimension extension lines
