Not at all. One of the benefits of using RELAX NG is that it supports
multiple namespaces [1]. You are free to embed SVG and XHTML markup
inside a DocBook document. This is perfectly valid [2]. From section
"Why switch to DocBook V5.0?" we have:
"DocBook V5.0 is more extensible. Having DocBook V5.0 in a separate
namespace allows you to easily mix DocBook markup with other XML based
languages like SVG, MathML, XHTML or even FooBarML."
