Form Post from Firefox

report=I get different answers for the same input. At first the answer 
was, that my document validated correctly, but it gave no triples. When 
I entered the same document again, the error message was: "Your document 
does not contain any RDF statement".
As my original documents almost looks like the example document, I do 
not understand this answer and would be grateful for any enlightment.

My original RDF/XML-document is:

<?xml version="1.0" encoding="UTF-8"?>
<rdf:rdf xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
         xmlns:dc="http://purl.org/dc/elements/1.1/">

   </rdf:Description>
</rdf:rdf>
