DOCBOOK-APPS: encoding XML

["Christopher J. Graham" <cjgraham@tachegroup.com>]

I am trying to encode an XML example as a programlisting entity.i am getting
the following errors. It works without the <?xml version="1.0"?>

I have the following:

<example>
  <title>An XML example</title>
  <programlisting>
    <![CDATA[
<?xml version="1.0"?>
<blah>this is an example</blah>
]]>
  </programlisting>
</example>
