 == MapServer `StyleObj` Extensions ==
 
- * Add a "name" property
- * Add a "global" property
+ * Add a "name" property to styleObj
+ * Add a "shared" property to styleObj
+   * Exporting a map file would emit all styleObjs with style.shared set to true at the top level
  * Add a "cloneStyle" function to mapfile.c
+   * This would be the programmatic interface for `EXTENDS`
+   * cloneStyle would presumably copy a top-level style and set the new object's `shared` property to false
