Nicolas,
David (Dr MathML) will probably be along shortly, but....
As you may know, XSLT (or any XML-namespace-conformant system) doesn't
distinguish between elements on the basis of their prefixes, but on the
basis of the expanded name when those prefixes are resolved to their URI
bindings. So if you have
<example xmlns:n1="myURL.com" xmlns:n2="myURL.com">
<n1:element/>
<n2:element/>
</example>
n1:element and n2:element are considered to be the same.
What this means is that you really only need an identity transform that
writes your output using the prefix you want.
This can probably be done (although I haven't tried it) very simply:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:math="http://www.w3.org/1998/Math/MathML ">
<xsl:template match="/">
<xsl:copy-of select="/"/>
</xsl:template>
</xsl:stylesheet>
This will work since the "math" prefix here is bound to the same URI as the
"mml" prefix in your input. (I'm assuming your input declares the correct
namespace. :-) And most XSLT engines should serialize the result using the
prefix you have chosen, "math". (Note however that strictly speaking they
don't have to do this: in effect you are relying on an optional feature of
the serializer, and you should test the technique on any processor before
depending on its working there.)
Cheers,
Wendell

I have an app that uses MathML, and gathers some stats from it.
But i ran into a problem when using mml tags embedded in docbook,
as this app uses the "math" prefix, and in docbook mathml tags
are prefixed with "mml".
I am trying to do a stylesheet that copies all mathml elements,
including attributes, data etc.. just changing the prefix.
Any idea ?
