839
           A full taxon name plus additional information can consist of the following elements:
840
          <ul>
841
             <li>name: the taxon name inclugin rank nbut without author</li>
842

843

             <li>microreference:  Volume, page number etc.</li>

             <li>status:  The nomenclatural status of a name</li>

           (The taxon name "Lapsana communis L., Sp. Pl.: 811. 1753" shall be an example in the following)

857
               This is useful for zoological names where the authorshipPart belongs to the name and both should</li>
858

859
            <li>referencePart: the nomencaltural reference (in example: "Sp. Pl. 1753")</li>
860
            <li>microreferencePart: usually the page number (in example ": 811.")</li>

          <ul>
869
