This approach I borrowed from one of Jeni Tennison's XSLT utilities.
<xsl:template match="math" xmlns:m=http://www.w3.org/1998/Math/MathML>
<xsl:variable name="name"><xsl:value-of
select="concat('m:',name(.))"/></xsl:variable>
<xsl:element name="{$name}">
<xsl:for-each select="@*">
<xsl:attribute name="{name(.)}">
<xsl:value-of select="."/>
</xsl:attribute>
</xsl:for-each>
<xsl:apply-templates mode="m"/>
</xsl:element>
</xsl:template>
This should accomplish exactly what you want. Giving every attribute and
element in <math> inclusive an m namespace prefix.

Presumably you want the result to be well-formed XML, in which case the
"m" namespace must be declared? If not (and perhaps anyway), your best
bet is to do a global replace using a text editor.
This is dynamic input from an html page component. I'm basically using
a Java-based MathML editor to let the user construct a formula. That
MathML-formatted formula is then fed through an html form input and
displayed in the subsequent page via Internet Explorer's Behavior
assigning
ability. The top of new page looks like this:
<html xmlns="http://www.w3.org/1999/xhtml";
xmlns:m="http://www.w3.org/1998/Math/MathML";>
<head>
<title>Variable on One Side</title>
<!-- Design Science MathPlayer -->
<object id="behave1"
classid="clsid:32F66A20-7614-11D4-BD11-00104BD3F987"><!-- --></object>
<?import namespace="m" implementation="#behave1" ?>
</head>
...
The behavior looks for all tags that are prefixed with the "m" namespace,
because that is what I instruct it to do in order to distinguish it from
html markup.
Giving the elements a prefix of "m" is cosmetic.
I thought it was required for the plugin to identify which elements
that
it is responsible for.
The key question is
what namespace you want the elements in. You haven't bound "m" to any
namespace. The spec says "the QName is expanded into an expanded-name
(ie., a namespace-uri/local-name pair) using the namespace declarations
in effect for the xsl:element element". It doesn't actually say what
happens if the prefix isn't in scope. Interestingly, this omission is
still present in the XSLT 2.0 draft. My interpretation has always been
that it is an error, but your XSLT processor seems to interpret it
differently, or to attempt a recovery action.
This is the result using MSXSL4.0:
<m:math xmlns="">
<m:apply xmlns="">
<m:power xmlns="" />
<ci>x</ci>
<cn>2</cn>
</m:apply>
</m:math>
This isn't well-formed XML, so I don't think any XSLT processor should
produce this result. Raise a bug report.
For the sake of succinctness in the original post, I left out the
wrapping tag that I generated in root-matching template that looked like
<result xmlns="http://www.w3.org/1999/xhtml";
xmlns:m="http://www.w3.org/1998/Math/MathML";>...</result>
Doesn't this satisfy the namespace definition?
3) Am I overcomplicating everything?
The key question is, are you trying to produce namespace-well-formed XML
output, and if so, what namespace do you want it in?
I want most of the output in the default namespace (for traditional
html
rendering) and small portions of it in the "m" namespace which is mapped
to
"http://www.w3.org/1998/Math/MathML";.
