Re: [docbook-apps] MathML XHTML howto

[kai brommann <kai_brommann@yahoo.com>]

hello again,

since now I have solved the problem on my own, I
decided to post the solution in case s.b. is
interested:

yes, this is the state of the art

> <mml:math

no, this mml namespace can stay as it is.

yes, for example use the following layer:

<?xml version='1.0'?>
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
version="1.0">
<xsl:import href="xhtml/chunk.xsl"/>
<xsl:template name="user.preroot">
<xsl:text
disable-output-escaping="yes">&lt;?xml-stylesheet
type="text/xsl" href="xsl/mathml.xsl"?>
</xsl:text>
</xsl:template>
<xsl:param name="html.ext" select="'.xhtml'"/>
</xsl:stylesheet>

thereby not only the additional line is there, but
also the files are renamed to .xhtml
(the latter could also be achieved by --stringparam
html.ext .xhtml of course). 
files with .html don't work, you need .xhtml or .xml
(unless there is some other configuration in your
browser)

> and what are the most recent (free) XSL files for

the four .xsl files from the w3.org URL mentioned
above seem to be one of the most recent free ones, but
perhaps there are others.

> I can put them on the same server as the
> XHTML files

yes, do this. it won't harm. and btw. it seems the
stuff is only working when served by a webserver (no
file:/// local browsing worked for me), perhaps
because of some MIME type setting?!

> Is it possible to get firefox display MathML content
markup within XHTML as of today (and not only
presentation markup)? 

yes (and perhaps IE works as well, I don't know and
who cares)

that's true. you are a friend of advocacy.

> thanx for your time and effort, 

no problem
