xmlns query for mathml

[Jon Thackray]

I'm trying to use the MathML DTD and stylesheets, but get some
problems with xmlns attributes. If I do something like

<math xmlns="http://...">
....
</math>

then xmllint and xalan in validating mode both complain that math
doesn't have an xmlns attribute. If I leave out the attribute, then
the Mathml stylesheet doesn't format the Mathml content using either
xalan or saxon.

Is the Mathml dtd wrong, or is there something else I should be doing?

I'm trying to use the MathML DTD

The MathML DTD declares xmlns as an attribute so you presumably have a
very old copy. MathML1 predates the XML Namespace Rec so not surprisingly
the very early versions did not declare xmlns.

the current DTD is (always) available from

http://www.w3.org/Math/DTD

in particular

http://www.w3.org/Math/DTD/mathml2/mathml2.dtd

Thanks, that works great, although I notice the "standalone" dtd isn't
very standalone. However, the tgz file does the job fine. I'm also
having a little trouble with the corresponding stylesheet (which I got
from http://www.w3.org/Math//XSL). I have a fragment such as

<math
xmlns="http://www.w3.org/1998/Math/MathML">
<mrow>
<munderover>
<mo>&product;</mo>
<mi>i=1</mi>
<mi>r</mi>
</munderover>
<mi>p</mi>
</mrow>
</math>

which I think should display a product (looking like a capital pi)
with i=1 underneath, r on top, and p to the right of it (used to be p
indexed by i, but I cut that out trying to simplify the problem). What
I actually get is the munderover part ok, but on a line on its own
with the p on the next line. The html that comes out of the stylesheet
is as below (I'm using pmathmlcss.xsl inside mathml.xsl, with output
method html). IE version 6 and Mozilla (from RH7.3) both display it
the same way, so I'm assuming the output markup must be wrong. Any
suggestions?
