One approach goes like this.
You have two DTDs.  One includes this:

   <!ELEMENT include EMPTY>
   <!ATTLIST include
      src CDATA #REQUIRED
      in  NMTOKEN #REQUIRED>

So you do things like

   <include src="snippets/flatten.erl" in="Erlang"/>

You have a program that reads the parsed form of the
file in either a SAX-like or DOM-like manner, and
processes the <include/> elements, generating whatever
markup is appropriate, and emits the complete result
as XML, ready for formatting.

*Manual* escaping is tedious and error-prone.
