validation problems

I entered the following urls into your schema validator:
http://users.rcn.com/rosenshield/courses.xml
http://users.rcn.com/rosenshield/schema.xsd

It gives me this error, which I don't quite understand:

The XML page cannot be displayed 
Cannot view XML input using XSL style sheet. Please correct the error and
then click the Refresh button, or try again later.

The download of the specified resource has failed. Error processing resource
'http://www.w3.org/2001/03/style/xsv.xsl'. 


Can you tell me what I am doing wrong? 

Thanks
