Google Calendar and iCalendar X-WR-CALNAME
I just figured out another Goggle Calendar idiosyncrasy:
When building an iCalendar (RFC 2445 / RFC 5545) feed, if you want to subscribe to that feed with Google Calendar, and you want to give your calendar a name, Google Calendar accepts the X-WR-CALNAME extension to the iCalendar standard, but it will only allow a text name if you add the parameter VALUE=TEXT, i.e.
X-WR-CALNAME;VALUE=TEXT:My Calendar Name
