The iCalendar spec (RFC 2445) says for the URL property:
   Description: This property may be used in a calendar component to
   convey a location where a more dynamic rendition of the calendar
   information associated with the calendar component can be found. This
   memo does not attempt to standardize the form of the URI, nor the
   format of the resource pointed to by the property value. 

On the other hand, it says about the ATTACH property:
   Purpose: The property provides the capability to associate a document
   object with a calendar component.
   Value Type: The default value type for this property is URI. The
   value type can also be set to BINARY to indicate inline binary
   encoded content information.


So, the URL is only for an alternative representation of the event itself. To 
append URLs with additional information or related documents, URL is the 
wrong property, and ATTACH is the correct one. As KOrganizer does not allow 
alternative representations of the event, we won't support the URL property. 

Cheers,

BTW: I've seen several calendars generated by Apple's iCal, that use 
   ATTACH;VALUE=URI:http://......
Is there any difference in iCal how to create ATTACH and URL properties. Is it 
possible to generate both? Or has the behavior changed somewhen?
