The problem is : you have a 3-ary relation between countr, ethnic group name and ethnic group percentage.
The only way to represent this in RDF is an intermediate resource like

<rdf:RDF
  xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
  xmlns:s="http://description.org/schema/">
  <rdf:Description ID="cid-Albania">
      <s:ethnicgroup>
        <rdf:Bag>

          <rdf:li>
            <rdf:Description>
              <s:name>Greeks</s:name>
              <s:percent>3</s:percent>
            </rdf:Description>
          </rdf:li>

          <rdf:li s:name="Albanian" s:percent="95"/>

        </rdf:Bag>
      </s:ethnicgroup>
  </rdf:Description>
</rdf:RDF>

note that the second <li> is much more compact, and is interpreted exactly the same way.

 hope this'll help
