rdf validation

Hi, 

I'm trying to Validate the bellow xml butit seems that I'm receiving an error on first line.

In case I'm removing from the firstline the next attributes, xmlns:xsi and xsi:schemaLocation, it seems that yourValidator is saying that the file is valid.

The Notepad++ validation is sayingthat there is an error into the xml file: Element '{http://www.w3.org/1999/02/22-rdf-syntax-ns#}RDF':No matching global declaration available for the validation root.

 

Can you please let me know whatshould I do to have a valid xml file on both sides?

 
Looking forward to receive an answer from you.Thanks and regards,Florin
