I don't think this is on topic for this mailing list, but anyway...

>From looking at the source code my guess is that ENSURE-DTD is called
too late in the P/DOCUMENT function.  You won't get this message if
the entity isn't in the first child:

                 (write-string "<test a='b'><child a='b&amp;'/></test>" s))
  "<test a='b'><child a='b&amp;'/></test>"

  CL-USER 35 > (cxml:parse-file "/tmp/example.xml" (cxml-xmls:make-xmls-builder))
  ("test" (("a" "b")) ("child" (("a" "b&"))))
