Math in Mallard

Hi Mallard list,

Is it possible to do mathematical formulae in Mallard using external
namespaces? As far as I can tell from the spec, the following should
work:

<span xmlns:m="http://www.w3.org/1998/Math/MathML">
  <m:math><m:mrow>
    <m:mi>n</m:mi><m:msup><m:mn>2</m:mn></m:msup>
    <m:mo>&#x2265;<!--geq--></m:mo>
    <m:mi>V</m:mi>
  </m:mrow>
</m:math></span>

Or does the processing tool also have to be aware of how to deal with
the external namespace?

Regards,
