Probably correct, if processors are operating correctly (big if),
given the following:
http://www.w3.org/2001/XMLSchema-instance
<?xml version="1.0" ?>
<!DOCTYPE xs:schema (View Source for full doctype...)>
- <xs:schema targetNamespace="http://www.w3.org/2001/XMLSchema-instance";
xmlns:xs="http://www.w3.org/2001/XMLSchema";

elementFormDefault="unqualified" attributeFormDefault="unqualified">

<h1>XML Schema instance namespace</h1>

This schema should never be used as such:
<a href="http://www.w3.org/TR/xmlschema-1/#no-xsi";>the XML Schema
Recommendation</a>
forbids the declaration of attributes in this namespace

</xs:documentation>

<xs:attribute name="nil" />
<xs:attribute name="type" />
<xs:attribute name="schemaLocation" />
<xs:attribute name="noNamespaceSchemaLocation" />
</xs:schema>
