/**
* $Id: VAvailability.java,v 1.10 2010/03/06 12:57:25 fortuna Exp $ [Apr 5, 2004]
*
* Defines an iCalendar VAVAILABILITY component.
*
*
Component Name: VAVAILABILITY
Purpose: Provide a grouping of component properties that describe
the availability associated with a calendar user.
Format Definition: A "VAVAILABILITY" calendar component is defined
by the following notation:
availabilityc = "BEGIN" ":" "VAVAILABILITY" CRLF
availabilityprop *availablec
"END" ":" "VAVAILABILITY" CRLF
availabilityprop = *(
; the following are REQUIRED,
; but MUST NOT occur more than once
dtstamp / dtstart / uid
; the following are OPTIONAL,
; but MUST NOT occur more than once
busytype / created / last-mod /
organizer / seq / summary / url /
; either 'dtend' or 'duration' may appear
; in a 'availabilityprop', but 'dtend' and
; 'duration' MUST NOT occur in the same
; 'availabilityprop'
dtend / duration /
; the following are OPTIONAL,
; and MAY occur more than once
categories / comment / contact / x-prop
)
