docs: Indicates if a JDom document is an RSS instance that can be parsed with the parser.
  <p/>
  It checks for RDF ("http://www.w3.org/1999/02/22-rdf-syntax-ns#") namespace being defined in
  the root element and for the RSS 1.0 ("http://purl.org/rss/1.0/") namespace in the channel
  element.
  
  @param document document to check if it can be parsed with this parser implementation.
  @return <b>true</b> if the document is RSS1., <b>false</b> otherwise.
