Hi docbook experts!

I am struggling to get MathML to work with htmlhelp. The only useful reference I found was this <http://markmail.org/thread/5kxwqwx3uihdytv2> thread on this list, where Dean seems to have got this to work. Unfortunately, repeating (at the best of my skills) his steps does not succeed for me.

As described, I made a customization layer xsl (see attachment modelon-htmlhelp.xsl). The transformation (xsltproc with docbook xsl 1.75.2) passes fine and a set of files (index.htm.xml, ch01.htm.xml, etc) are generated. The generated xml files have the head elements (before <html>):
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<?xml-stylesheet type="text/xsl" href=""?><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0  
Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
Compilation with MS help compiler generate the warnings described in Dean's post and a chm file is generated.

Now, opening  the .chm file shows the document outline but not page contents.  The following error is displayed:

The XML page cannot be displayed

Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.


System error: -2146697204. Error processing resource 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd'.


The same error is reported when opening index.htm.xml in IE 8. It displays fine in Firefox.

I am quite new to docbook and xslt, so I may have misinterpreted the instructions. Any help or hints to what is wrong would be very much appreciated.

I got xhtml output to work on IE (see attachment modelon-xhtml.xsl), using the header tags
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1 plus MathML 2.0 plus SVG 1.1//EN" "http://www.w3.org/Math/DTD/mathml2/xhtml-math11-f.dtd">
I also tried this dtd with htmlhelp, but without success.

Again, I would be much grateful for any hints or help on this matter.

/Magnus
