Description
Word or phrase occurring in
the text that is to
appear in the index under as a primary entry. It must be
nested within IndexTerm tags. Primary may contain in-line
elements. It has SortAs and common attributes.
SortAs can be used to provide
an alternate string for alphabetizing the index: if Primary
has the content "14"
one might give Primary the attribute
Sortas="fourteen".
In some contexts, some of these elements
may be invalid due to exclusions in parent elements.

Examples
<CHAPTER>
<TITLE>A Chapter About IndexTerms</TITLE>
<PARA>IndexTerm can be an inclusion at the book component level;
an example beginning at the paragraph level won't parse.</PARA>
<PARA>This paragraph deals with two subjects that should
be listed in
the index: how to rotate your terminal and how to adjust
it. The information on rotation goes in the index
to the current document; that on adjustment goes in that
index and the index to the document set of which the
current document is a part.
<INDEXTERM SCOPE="local" SIGNIFICANCE="preferred">
<PRIMARY>rotating your terminal

</INDEXTERM>
For the topic of rotation, this is the best place to look
for information, so the
<SGMLTAG CLASS="attribute">Significance</SGMLTAG> attribute is set to
“Preferred”.
