Simple Register Form

Registers are enclosed by <div> elements, which get the attribute value pair @type="index".

The actual register is then structured in the form of a list (<list>), in doing so each register entry is recorded in a <item> element.

The page numbers in the register entry are enclosed within the <item> element with a <ref> element. Each page number is assigned a separate <ref> element, even if the page numbers are placed directly behind each other. Any punctuation marks are located outside the <ref> elements.

If register entries have sub-entries, they are tagged as nested lists.

    <list>
    <item>[keyword1]
    <ref target="#[page number1]">[page number1]</ref>
    <ref target="#[page number2]">[page number2]</ref>
      </item>
      <item>[keywordX]
      <ref target="#[page numberX]">[page numberX]</ref>
      </item>
    </list>
  </div>
