.net 6.0 XSD validator bug

Hi all,

Please refer the following link, https://docs.microsoft.com/en-us/dotnet/standard/data/xml/xml-schema-xsd-validation-with-xmlschemaset.

I run the C# example, posted on the above cited page using the mentioned XSD and XML documents. I get an XSD valid assessment.

But if within the XML document books.xml, I specify the first line as following,

<bookstore xmlns="http://www.contoso.com/books1"> (please note that, I specify the namespace value different than the value of targetNamespace attribute specified within XSD document)

I still, get an XSD valid outcome. It seems to me that, .net 6.0 (and perhaps for other .net versions as well) XSD validator has this bug while XML schema validation with XSD targetNamespace attribute.

Does anyone else also feels that, the XML schema validation example I've cited above, is a bug with .net XSD validator? As of .net 6.0, is there any workaround to get the above cited example working, according to XML schema 1.0 spec.
