Well, "you could change the DTD in a non-intrusive way" with by adding
a local DTD part to your document, that would make this element valid.
Since programlisting itself does not have a hook, but mostly contains
%para.char.mix;, you can just add to the latter, which BTW also allows
the xinclude element in many other places.  The following is untested,
but you get the idea.

<!DOCTYPE .... [
<!ELEMENT xi:include ....>
<!ATTRIBUTES xi:include ....>
<!ENTITY % local.para.char.mix "|xi:include">
]>
