| <para> |
| If non-zero, |
| then an <tag>index</tag> element that has a |
| <tag class="attribute">type</tag> attribute |
| value will contain only those <tag>indexterm</tag> |
| elements with a matching <tag class="attribute">type</tag> attribute value. |
| If an <tag>index</tag> has no <tag class="attribute">type</tag> |
| attribute or it is blank, then the index will contain |
| all <tag>indexterm</tag>s in the current scope. |
| </para> |
| |
| <para> |
| If <literal>index.on.type</literal> is zero, then the |
| <tag class="attribute">type</tag> attribute has no effect |
| on selecting indexterms for an index. |
| </para> |
| |
| <para>For those using DocBook version 4.2 or earlier, |
| the <tag class="attribute">type</tag> attribute is not available |
| for index terms. However, you can achieve the same |
| effect by using the <tag class="attribute">role</tag> attribute |
| in the same manner on <tag>indexterm</tag> |
| and <tag>index</tag>, and setting the stylesheet parameter |
| <parameter>index.on.role</parameter> to a nonzero value. |
