I think I understand what you are trying to do. You can't use system entities if you want your math file to include a doctype for editing purposes. But you can use xinclude. You could have your first XSL transform your source file to produce the following output in your generated Docbook document at the point where you want the math to appear: <xi:include href="math.xml" xmlns:xi="http://www.w3.org/2001/XInclude"/> The math.xml file can look something like this: <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE m:math PUBLIC "-//W3C//DTD MathML 2.0//EN" "http://www.w3.org/TR/MathML2/dtd/mathml2.dtd"; [ <!ENTITY % MATHML.prefixed "INCLUDE"> <!ENTITY % MATHML.prefix "m"> ]> <m:math xmlns:m="http://www.w3.org/1998/Math/MathML";> <m:mrow> <m:mrow> <m:msup> <m:mi>x</m:mi> <m:mn>2</m:mn> </m:msup> <m:mo>+</m:mo> <m:mrow> <m:mn>4</m:mn> <m:mo>⁢</m:mo> <m:mi>x</m:mi> </m:mrow> <m:mo>+</m:mo> <m:mn>4</m:mn> </m:mrow> <m:mo>=</m:mo> <m:mn>0</m:mn> <m:mo>=</m:mo> <m:mn>0</m:mn> </m:mrow> </m:math> Then process the file using xsltproc with the --xinclude option: xsltproc --xinclude ../docbook-xsl-1.52.2/xhtml/docbook.xsl generated.xml Or use fo/docbook.xsl for print output. The DocBook stylesheets will pass the math through. The resulting xhtml file will include: <m:math xmlns:m="http://www.w3.org/1998/Math/MathML"; overflow="scroll"> <m:mrow> <m:mrow> <m:msup> <m:mi>x</m:mi> <m:mn>2</m:mn> </m:msup> <m:mo>+</m:mo> <m:mrow> ... What happens to it then depends on your browser or FO processor. -- Bob Stayton 400 Encinal Street Publications Architect Santa Cruz, CA 95060 Technical Publications voice: (831) 427-7796 Caldera International, Inc. fax: (831) 429-1887 email: bobs@caldera.com
