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?
