Section 3.8.5.1 says:

   Purpose:  This property defines the list of DATE-TIME exceptions for
   recurring events, to-dos, journal entries, or time zone
   definitions.

...

   Conformance:  This property can be specified in recurring "VEVENT",
   "VTODO", and "VJOURNAL" calendar components as well as in the
   "STANDARD" and "DAYLIGHT" sub-components of the "VTIMEZONE"
   calendar component.

It should say:

   Purpose:  This property defines the list of DATE-TIME exceptions for
   recurring events, to-dos or journal entries.

...

   Conformance:  This property can be specified in recurring "VEVENT",
   "VTODO", and "VJOURNAL" calendar components.

Notes:

Section 3.8.5.1 describes Exception Date-Times (EXDATE).

tzprop (section 3.6.5) does not allow EXDATE.

(Of course, the problem could be that 3.6.5 should include EXDATE.)
