[Vincent Lefevre <vincent@vinc17.net>]

Package: w3-dtd-mathml
Version: 2.0.0.0-2
Severity: normal

/etc/xml/catalog doesn't contain a reference to the MathML DTD.

With the example from Wikipedia:

xvii:~> cat example.mml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE math PUBLIC "-//W3C//DTD MathML 2.0//EN"
  "http://www.w3.org/Math/DTD/mathml2/mathml2.dtd";>
<math xmlns="http://www.w3.org/1998/Math/MathML";>
  <mrow>
    <mi>a</mi>

    <msup>
      <mi>x</mi>
      <mn>2</mn>
    </msup>
    <mo>+</mo>

    <mo>&#x2062;<!-- &InvisibleTimes; --></mo>

    <mo>+</mo>
    <mi>c</mi>
  </mrow>
</math>

There are no calls to update-xmlcatalog in the postinst script,
contrary to the postinst script of docbook-mathml, for instance.

A dependency on xml-core (>= 0.05) should probably be added too
(like docbook-mathml).
