DOCBOOK: including literal html in docbook documents

I'm struggling with the following issue: displaying included
external HTML documents. I would like to keep the documents
externally (say in foobar.html) and display them literally
in a docbook document.

I unfortunately do not know how to get it right -- can someone
help me?

I define an entity in beginning:
<!ENTITY foo SYSTEM "foobar.html">

and want to display it later "as is":
<programlisting>
<![CDATA[
&foo;
]]>

Unfortunately &foo is printed literally because of used CDATA.
When I do not use CDATA, the html document will be interpreted
which I do now wish to do.

Thanks,

-Jiri
