I'm trying to embed some RDF metadata in my XML documents. I use Xerces-J
XML parser to read and validate the documents, so tried the following: 

<?xml version="1.0"?>
...
<rdf:RDF 
  xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
  xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
  xsi:schemaLocation="http://www.w3.org/1999/02/22-rdf-syntax-ns#
                      http://www.w3.org/2000/07/rdf.xsd">
...                             
</rdf:RDF>

But the parser don't like the "http://www.w3.org/2000/07/rdf.xsd" XML
Schema because it's written in an older specification
("http://www.w3.org/1999/XMLSchema") than the current
("http://www.w3.org/2001/XMLSchema").

I found similar problems with the XML Schema for Dublin Core Metadata
located at
"http://dublincore.org/documents/2001/04/11/dcmes-xml/dcmes-xml-xsd.xsd".

So, 

1) Is there any XML Schema for RDF conforming the
"http://www.w3.org/2001/XMLSchema" specification?

2) If no, how can I validate an XML including RDF metadata using a XML
parser like Xerces?

Thanks in advance.
