Confirmation: the syntax of the <data> pattern.

I understand that <data> pattern is defined as attached (at the moment.)

Please let me know if something is wrong with it.


One question:

  @key and @keyref are exclusive? I can't imagine a situation where both
  are used at the same time, but certainly it doesn't do any harm.

Another question:

  Is there any chance that @type is introduced for <attribute>? That
  would be just a short cut for
  
  <attribtue><data type="..."/></attribute>

  I'm not sure if I really want to have this....
