I'm test driving the 12/17 Schema WD support and think I found a bug...
Specifying an attributeGroup reference in a type declaration causes an error if
at least one attribute isn't defined before it. The error is: "Datatype
qualifiers can only be used if you specify a type attribute." Although the
syntax changed, this should still be legal.
Using the sample DOMCount or SAXCount, the following short test files will
reproduce the problem. A stack trace only shows up if you modify DOMCount or
SAXCount to print it (which I did and the trace is appended below).
