This section contains examples of how <index-see-also> elements can be used.

Example 1. Use of an <index-see-also> element

The following code sample shows the use of an <index-see-also> element to generate a "see also" reference to the index entry for "goldfish". 

<indexterm>carp
  <index-see-also>goldfish</index-see-also>
