Further to a point raised by Sandy Gao at http://www.w3.org/Bugs/Public/show_bug.cgi?id=8119#c4, I think we should make a modest correction.

At the moment, in the section on Attribute Groups [1], we have

  "No two distinct members of the {attribute uses} have
   {attribute declaration}s with the same expanded name."

whereas in the section on Complex Type Definitions [2], we have

  "No two distinct attribute declarations in the {attribute uses}
   have identical expanded names."

I think we should use the same wording in both cases, and I think the first wording is the right wording.
