+ * The <code>substring-after</code> function returns the substring of the
+ * first argument string that follows the first occurrence of the second
+ * argument string in the first argument string, or the empty string if the
+ * first argument string does not contain the second argument string. For
+ * example, substring-after("1999/04/01","/") returns 04/01, and
+ * substring-after("1999/04/01","19") returns 99/04/01.
