The <s> tag is inline markup within a <para> element. Any text it encloses is displayed with strong emphasis. It is used to mark a piece of text as being very important. Moderately important text should be marked up using the normal emphasis tag <e> .

<para>
</para>
</sect1>
An <s> may only contain basic text.
Strongly emphasised text should be displayed in bold at the same size and style as the surrounding text.
