Oleg Paraschenko has released TeXML 2.0, an XML vocabulary for TeX. The processor that transforms TeXML markup into TeX markup is written in Python, and thus should run on most modern platforms. According to Paraschenko, "The main new feature is an automatic laying out of the generated LaTeX code. In fully automatic mode, the TeXML processor deletes redundant spaces and splits long lines on smaller chunks. The generated LaTeX code is legible enough for humans to read and modify." TeXML is now published under the MIT/X Consortium license..
