programlisting

Processing Expectations

Formatted as a displayed block. This element is displayed “verbatim”; whitespace and linebreaks within this element are significant. ProgramListings are usually displayed in a fixed width font.

Other markup within a ProgramListing is recognized. Contrast this with systems like LaTeX, in which verbatim environments disable markup recognition. If you want to disable markup recognition, you must use a CDATA section:

<programlisting>
<![CDATA[
This is a programlisting so white       space and line
breaks are significant.  But it is also a CDATA
section so <emphasis>tags</emphasis> and &entities;
are not recognized.  The only markup that is recognized
is the end-of-section marker, which is two
"]"'s in a row followed by a >.

]]>

</programlisting>

Two markup tags have special significance in ProgramListings: CO and LineAnnotation. A CO identifies the location of a Callout. A LineAnnotation is a comment, added by the documentor—not the programmer.
