Specifies a time range to limit the set of "overridden components" returned by the server.
The CALDAV that for a given calendaring REPORT request, the server MUST return, in addition to the "master component", only the "overridden components" that impact a specified time range. An overridden component impacts a time range if its current start and end times overlap the time range, or if the original start and end
times -- the ones that would have been used if the instance were not overridden -- overlap the time range.
The "start" attribute specifies the inclusive start of the time range, and the "end" attribute specifies the non-inclusive end of the time range. Both attributes are specified as date with UTC time value. The value of the "end" attribute MUST be greater than the value of the "start" attribute.
The server MUST use the same logic as defined for CALDAV:time- range to determine if the current or original scheduled time of an "overridden" recurrence instance intersects the specified time range.
Overridden components that have a RANGE parameter on their RECURRENCE-ID property may specify one or more instances in the recurrence set, and some of those instances may fall within the specified time range or may have originally fallen within the specified time range prior to being overridden. If that is the case, the overridden component MUST be included in the results, as it has a direct impact on the interpretation of instances within the specified time range.
