Subject: Re: [docbook-apps] Docbook5.0b4 mathml xsltproc fop
I'm not sure what you are expecting, but fop 0.20.5 does not support MathML processing. The stylesheet just passes MathML content through, on the assumption that the downstream processor can typeset it in some way. But fop cannot process it, and indicates so in the error messages. You can preprocess your math into an SVG image, and use a mediaobject inside your informalequation to reference the SVG file.
