docs: Add an element with character data content but no Namespace URI or qname.
  
  <p>This is a convenience method to add a complete element
  with character data content, including the start tag
  and end tag.  The method provides an empty string for the
  Namespace URI, and empty string for the qualified name. It invokes
  {@link #dataElement(String, String, String, Attributes, String)}}
  directly.</p>
  
  @param localName The element's local name.
  @param atts The element's attributes.
  @param content The character data content.
  @exception org.xml.sax.SAXException If a filter
  further down the chain raises an exception.
