saxonMeta/Wild.testSet has two entries for the same combination: "wild059.xsd" + "wild058.n2.xml".

Both are marked "valid", but the documentation suggests that they are invalid "zong attribute is not present in the intersection of the attribute groups."

The instance has

<zing zong="12:00:00"/>

But the attribute wildcard in "zing" has ##defined excluded, and "zong" is a globally declared attribute, so should not be allowed to appear on "zing". Suggest to change the expected validity to "invalid".
