| 15 | | * <p>This is discussed in <div xlink:href="example.xml#xpointer(id('4711')/div[1])">the first division of the example document</div>.</p> |
| 16 | | * <p>This is discussed in <div xlink:href="example.xml#element(/1/2)">the second element of the first element</div>.</p> |

| 29 | | ==== Range ==== |
| 30 | | * xpointer(id("chap1")/range-to(id("chap2"))) (the range from the start point of the element with ID "chap1" to the end point of the element with ID "chap2") |
