Hi, Thanks for a detailed response. Let met give some examples, I am mainly using math in two ways (i) inline math and (ii) math displayed on its own. The inline math is enclosed in '$' and here is an example of it, Given the HMM model ($\lambda$ = (A, B, $\pi$)) and a sequence of symbols $O = <O_1, O_2, \dots ,O_T>$, what is the probability that this sequence was generated by the model ? If I want to write equations that won't fit on a line then I go with the display math option for example, \[\alpha_t(i) = P(O_1, O_2, \dots O_t, q_t = S_i \lambda)\] Here the math is enclosed in \[ and \]. Both these options are currently supported by itex2mml. So if you give itex2MML an html document with these tags it will convert them to mathML. About your suggestion I think I will use the texmath:: directive for displaying equations that won't fit in a line, but using it for inline might be a bit cumbersome. MathML is very verbose format so I don't think I will be directly typing mathml in any of my documents. I will stick with Tex math notation as it is widely used and easy to understand. Let me see if I can implement the texmath:: directive and tie it with itex2mml. I will keep you posted...
