Today i was reading the iCalendar (proposed?) standard because (possibles) changes in my country calendar. One of them is add the Lent (Cuaresma, quadragesima) days as holiday. Someone in this forum talk about a week holiday in the 42nd week of the year.
Searching in the IETF RFCs i found: RFC 2445 (iCalendar), RFC 5545 (iCalendar) and RFC 5546 (iTIP). I'm sure you know this 3.
The item 3.2.15. Relationship Type
To specify the type of hierarchical relationship associated with the calendar component specified by the property.
This property is intended only to provide information on the relationship of calendar components. It is up to the target calendar system to maintain any property implications of this relationship.
The item 184.108.40.206. Non-Standard Properties
Property Name: Any property name with a "X-" prefix
I know that there are not 2 equals iCal applications, but i thought that it would be a good thing to add something different in Rainlendar. eg:
I know all the effort you do to maintain your app, and i don't know if this is possible, even maybe this only will work in Rainlendar... but the Rainlendar users will be grateful.
