No direct way, no. I can think of one indirect way and several direct ways to do what you want. The best, direct way would be to create a new directive. If you want TeX notation in your source text files, there could be a "texmath" directive. For TeX output, the TeX code would be passed through untouched. For output formats supporting MathML, the TeX code would call itex2mml and insert the resulting MathML markup into the document. For output formats that don't support MathML, perhaps a MathMLtobitmap rendering tool could be used, and the resulting image inserted into the document. For example:: .. texmath:: (raw TeX math code here) If you want to use MathML directly, you could use the "raw" directive to pass the markup through to the HTML writer (and only the HTML writer), like this:: .. raw:: html <math xmlns="..."> raw HTML/MathML here </math> You could use this approach right now. A new "mathml" directive would be even better. It would be able to take care of the bookkeeping details details (like the <math> tags, namespaces, and output format compatibility issues):: .. mathml:: (raw MathML here) Finally, there's a quick & dirty indirect way to use TeX code, without any programming. Use the "raw" directive with the TeX code between "$", and preprocess the file with itex2mml. (I assume itex2mml removes the "$" characters? If not, this won't work without another step to remove them.) :: .. raw:: html $(raw TeX math code here)$ There may be other associated issues, like declaring a MathML namespace and/or a DTD declaration.
