	 * dynamically assigned to a String field that was defined as char(6).  The actual java field type will be java.lang.String.  However
	 * the TypeConstraints for that field will have a reference to Class egl.lang.Char.class as well as the length of 6.  This information
	 * will be used to then truncated the string of length 10 to one of length 6.
