L.1.14.8 Bookmarks

A bookmark refers to an arbitrary region of content that is bounded and has a unique name associated with it.

Because bookmarks are a legacy word-processing function that predates the concepts of XML and well- formedness, they can start and end at any location within a document’s contents and, therefore, must use the cross-structure annotation format described in L.1.14.3.

Consider the following WordprocessingML markup for two paragraphs, each reading Example Text, where a bookmark has been added spanning the second word in paragraph one and the first word in paragraph two:

<w:p>
  <w:r>
    <w:t>Example</w:t>
  </w:r>
  <w:bookmarkStart w:id="0" w:name="sampleBookmark" />
  <w:r>
    <w:t xml:space="preserve"> text.</w:t>
  </w:r>
</w:p>
<w:p>
  <w:r>
    <w:t>Example</w:t>
  </w:r>
  <w:bookmarkEnd w:id="0" />
  <w:r>
    <w:t xml:space="preserve"> text.</w:t>
  </w:r>
</w:p>

The bookmarkStart and bookmarkEnd elements specify the location where the bookmark starts and ends, but cannot contain it using a single tag because it spans parts of two paragraphs. However, the two tags are part of one group because the id attribute value specifies 0 for both.
