[Ietf-calsify] Section 4.8.2.5 Duration: VFREEBUSY request

[Bernard Desruisseaux]

In section 4.8.2.5 Duration of RFC 2445 it says:

 > In a "VFREEBUSY" calendar component the property may be
 > used to specify the interval of free time being requested.

Yet, section 3.3.2 REQUEST of RFC 2446 (iTIP) specifies that
the DURATION property is not allowed in a VFREEBUSY request.

I see three options:

a) Remove statement from iCalendar to be in sync with iTIP;

b) Change iTIP to allow the DURATION property in a VFREEBUSY
    request and define the semantic as specified in iCalendar.

c) Status quo.

Cheers,
Bernard
