          Implementor’s Note: No attempt has been made to retain the look or
          visual form of the original poetry.
  
          This unusual element, <verse-group> is used to convey poetry and is
          recursive in nature (it may contain further <verse-group> elements).
          Examples of these tags are sparse, so it remains difficult to ensure
          full implementation. This method will attempt to handle the label,
          title, and subtitle elements correctly, while converting <verse-lines>
          to italicized lines.
