title: "not done yet" Exception when running FHIR Validator
body: <p>I downloaded the Jar File for the FHIR Validator. Then I ran the Validator as per the instructions on the HL7 Website. I ran the following command from cmd:</p>
  
  <p>java -jar org.hl7.fhir.validator.jar Composition.xml -defn validation-min.xml.zip </p>
  
  <p>I downloaded both the resource file and the validation package on the desktop. But I get the following error</p>
  
  <pre><code>java -Xmx512m -jar org.hl7.fhir.validator.jar Composit
  ion.xml -defn validation.xml.zip
