Have you tried using the namespace declaration in your document?
Something like this:
<?xml version="1.0" encoding="utf-8"?>
<article
xmlns='http://docbook.org/ns/docbook'
xmlns:xlink='http://www.w3.org/1999/xlink'
xmlns:mathml="http://www.w3.org/TR/MathML2/dtd/mathml2.dtd";
version="5.0" xml:lang="en">
<title>Title of your document</title>
This should replace the entity declaration and still let your mathml validate.
HTH,
