Thanks! I am glad to hear MSXML allows this to be detected.

Now suppose I change example.xml to:

<bar xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
   xsi:noNamespaceSchemaLocation="bar.xsd"/>

where bar.xsd is:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>

<xs:element name="bar">
  <xs:complexType/>
</xs:element>

</xs:schema>

Is there also some way to tell MSXML not to allow the instance to provide
additional schemas so that this would be detected as invalid as well?
