If you are talking about recurrence_month_date events, then your  
client is broken. These properties make no sense with this recurrence  
type. For the recurrence_month_day type, they are already sent.

Yes, it does. I'm on my mobile right now so I can't give a link, but  
it's there.

Impossible, it's not defined in any of the wbxml codepages/schema for EAS 2.5

Yes. If your client requires this for EAS 2.5 then it's broken, or  
doesn't support 2.5.

  In this context, It's the first week with any days in the month.  
Nothing else would make sense since the recurrence types that use this  
recur on e.g., the first tuesady of the month. Any other definition  
would potentially miss days in the first week.

Not without hacking the kronolith code. I agree it's a potential  
issue, but don't think we shuld limit our feature set based on a  
limited sync protocol.
