Major Editorial:
Line 664: change"EMIX, which itself incorporates WS-Calendar" to "EMIX, which defines Schedules and types conforming to WS-Calendar"
Line 671: change "are here" to "are listed here"
Line 711 wording ..."and nothing herein is meant to redefine or modify those definitions" – compare to wording on line 670-671. The earlier lines are before the table, the 711 line is after. Put both before their respective tables and make the wording the same.
