[Xcb] Working on RandR 1.2 proto

[Ian Osgood]

OK, I've hit the first XSLT limitation.

RandR 1.2 defines one new event ("Notify") which has three subCodes  
(specified using the CARD8 hole between event type and sequence  
number). Unfortunately, the remainder of the event structure is  
completely different between these three subcodes. Currently, our  
XSLT doesn't allow us to overload event numbers with different event  
structures like this.

Is this a useful enough pattern in extensions for us to extend our  
XML descriptions with an optional subcode?  Like so:

   <event name="CrtcChangeNotify" number="1" subcode="0">
     <!-- subcode is specified, so no need to delcare or pad the  
CARD8 hole -->
   </event>

   <event name="OutputChangeNotify" number="1" subcode="1">
   </event>

   <event name="OutputPropertyNotify" number="1" subcode="2">
   </event>

Or should we ask Keith to use standard event numbering, introducing  
three new events instead of one event with three subcodes?
