 <para>
  {literal} tags allow a block of data to be taken literally. This is typically
  used around javascript or stylesheet blocks where curly braces would
  interfere with the template
  <link linkend="variable.left.delimiter">delimiter</link>
  syntax. Anything within
  {literal}{/literal} tags is not interpreted, but displayed as-is. If you
  need template tags embedded in your {literal} block, consider using <link
  linkend="language.function.ldelim">{ldelim}{rdelim}</link> to escape the
  individual delimiters instead.
