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