+# 
+# From the RFC:
+# The calCalURI contains the URI to a snapshot of the user's entire
+# default calendar. The calFBURL contains the URI to the user's default
+# busy time data. The calCAPURI represents contains a URI that can be
+# used to communicate with the user's calendar. The calCalAdrURI
+# contains a URI that points to the location to which event requests
+# should be sent for that user.
+#
+# The calOtherCalURIs is a multi-valued property containing URIs to
+# snapshots of other calendars that the user may have. The
+# calOtherFBURLs is a multi-valued property containing URIs to other
+# free/busy data that the user may have. The calOtherCAPURIs attribute
+# is a multi-valued property containing URIs to other calendars that
+# the user may have. The calOtherCalAdrURIs attribute is a multi-valued
+# property containing URIs to other locations that a user may want
+# event requests sent to.
+#
+# There is no predetermined order to the values in either multi-valued
+# property.
