# s.indexterm

## Syntax

**s.indexterm**

## Purpose

## Example

The following is the DITA XML output for the previous rule:

<conbody>

<p>A</p>

<p><indexterm>accelerometer</indexterm>. <indexterm><index-see>See electronic components</index-see></indexterm></p>

<p><indexterm>assembling</indexterm>, 14</p>

<p>            <indexterm>connecting coolant lines</indexterm>, <i>14</i></p>

<p>            <indexterm>connecting fuel lines</indexterm>, <i>15</i></p>

<p><indexterm>assembly</indexterm>. <indexterm><index-see>See assembling</index-see></indexterm></p>
