 * is the highest priority.  A value of 2 is the second highest
 * priority.  Subsequent numbers specify a decreasing ordinal
 * priority.  A value of 9 is the lowest priority.
 *     
 * Example:
 * The following is an example of a property with the highest priority:
 * PRIORITY:1
 *  
 * @author David Bal

 * The property can be specified in following components:
