How to cause XML parser to fail validation

How to cause MS XML Parser to fail validation, if it does not find external XML schema specified in the XML document?

Right now it just ignores that a returns that validation caused successfully.

I use MS Visual C++, MFC however it's a COM Object, so it's the same is in .NET.

Thanks

Consider reading out the xsiTongue TiedchemaLocation or xsi:noNamespaceSchemaLocation attribute with your code and then have it test whether the schema(s) can be loaded.
