The sForS is not a valid schema and thus should fail to validate. As for
validating processors to allow 

<xs:import  namespace="http://www.w3.org/2001/XMLSchema" />

so users can specify items from the http://www.w3.org/2001/XMLSchema
namespace in their instance documents is a work around to this
deficiency that I am not sure any validating processor currently
implements. I had heard that recent versions of XML Spy allow one to do
this but have not actually tried the product out to confirm.
