<para>
<sgmltag>Replaceable</sgmltag> is used to mark text that describes
<emphasis>what</emphasis> a user is supposed to enter, but not the
<emphasis>actual text</emphasis> that they are supposed to enter.
</para>
<para>
It is used to identify a class of object
in the document, in which the user is expected to replace the text that
identifies the class
with some specific instance of that class.  A canonical example is
<screen>
<![CDATA[
<replaceable>filename</replaceable>
]]>
</screen>
in which the user is expected to provide the name of some specific file
to replace the text <quote>filename.</quote>
</para>

<para>
&format.inline; Usually, the text is given special typographic treatment,
such as italics, as a clue to the user that this is replaceable text.
Often the font used is described in a <quote>conventions</quote> section at
the beginning of the document.
