Hazard-statement domain elements
    
     The 
<hazardstatement> domain adds
      markup to support hazard statements. It is based on the regulations
      of ANSI Z535 and ISO 3864. The domain enables authors to provide all
      the information necessary for a hazard statement: a signal word,
      description of the hazard and its consequences, how to avoid the
      hazard, and one or more images.
