Mark Wielaard 555ddc4753 Use DTD DocBook XML V4.5 everywhere.
This makes the rule for xmllint easier since it doesn't need to
override the DTD to validate against. It also helps with other tools
tryinf to process the docbookx xml files.

<title>Overview</title>
<para>Nulgrind is the simplest possible Valgrind tool. It performs no
instrumentation or analysis of a program, just runs it normally. It is
mainly of use for Valgrind's developers for debugging and regression
testing.</para>
<para>Nonetheless you can run programs with Nulgrind. They will run
roughly 5 times more slowly than normal, for no useful effect. Note
that you need to use the option <option>--tool=none</option> to run
Nulgrind (ie. not <option>--tool=nulgrind</option>).</para>
