Which schema validation tool are you using?  It appears that you are not using a validator that is updated to the final recommendation.  The use attribute with default or fixed was removed from the final spec.

    This is not the correct way of using it though.... 
    If you want to use the xml:space or xml:lang attributes in your schema you have to declare 
    them by reference and import the XML namespace from W3C. You can't "redeclare" the 
    attributes as in the above schema. 
    So, first you have to import the XML namespace using the import statement like: 

    <xs:import namespace="http://www.w3.org/XML/1998/namespace" 
    schemaLocation="http://www.w3.org/2001/xml.xsd"/> 

    You also have to add a namespace declaration on your xs:schema element. Like: 

    <xs:schema ...xmlns:xml="http://www.w3.org/XML/1998/namespace"...>... 

    No, you can reference the attributes defined by this namespace in your own schema using: 

    <xs:attribute ref="xml:lang"/> 

    Hope this helps.
