24 <para>If zero, then an index entry in an index links | |
25 directly to the location of the | |
26 generated <tag>anchor</tag> that is output | |
27 for the indexterm. If two identical indexterm elements | |
28 exist in the same section, then both entries appear | |
29 in the index with the same title but link to different | |
30 locations.</para> | |
31 | |
32 <para>If non-zero, then an index entry in an index links to the | |
33 section title containing the <tag>indexterm</tag>, rather than | |
34 directly to the <tag>anchor</tag> output for the indexterm. | |
35 Duplicate indexterm entries in the same section are dropped. | |
36 </para> | |
37 | |
38 <para>The default value is 1, so index entries link to | |
39 section titles by default.</para> | |
40 | |
41 <para>In both cases, the link text in an index entry is the | |
42 title of the section containing the indexterm. | |
43 That is because HTML does not have numbered pages. | |
44 It also provides the reader with context information | |
45 for each link.</para> | |

47 <para>This parameter lets you choose which style of | |
48 index linking you want. </para> | |

52 <para>When set to 0, an index entry takes you | |
53 to the precise location of its corresponding indexterm. | |
54 However, if you have a lot of duplicate | |
55 entries in sections, then you have a lot of duplicate | |
56 titles in the index, which makes it more cluttered. | |
57 The reader may not recognize why duplicate titles | |
58 appear until they follow the links. Also, the links | |
59 may land the reader in the middle of a section where the | |
60 section title is not visible, which may also be | |
61 confusing to the reader.</para> | |
62 </listitem> | |
63 <listitem> | |
64 <para>When set to 1, an index entry link is | |
65 less precise, but duplicate titles in the | |
66 index entries are eliminated. | |
67 Landing on the section title location may confirm the reader's | |
68 expectation that a link that | |
69 shows a section title will take them to that section title, | |
70 not a location within the section. | |
