[Xcb] xml schema

For the most part, strings are lists of "char" and lists of small
integers are lists of "BYTE", "CARD8", or "INT8".

I haven't audited the entire code base to see if this convention is used
consistently. A patch to fix any deviations would be appreciated.

Aside: PolyText(8|16) is a troublesome case that needs to be a list of
(something that contains a <switch>) instead of "BYTE", since "char"
wouldn't be correct in the current description either.
