Hi, I've just looked at three documents from Hans ('mmlexamp.pdf', 'mmlprime.pdf', 'mmoexamp.pdf'), and they all show nice examples of MathML and what you can accomplish using it. However, I wasn't able to find an example of how to actually insert MathML in a Context document. I imagine it's probably something like that: \starttext (...) \startMathML (...) \stopMathML (...) \stoptext Does anyone knows of an example on how to do that properly? Thanks, Maurício
