Here is something that was not in my original list: subformula numbering.
[...]
I was thinking of a better (rather more familar) way of treating subformulas by imitating the \begin{subequations} .... \end{subeqations} environment of latex.
I propose a \startsubformula .... \stopsubformula environment, so that inside it, I will get subformula numbers rather than formula numbers. Having discovered conversions (see my previous mail on tagged formulas), I tried to implement it using conversions. The following straightforward approach works fine. This is just a stop gap code, I do not take care of inherting the right settings for formulas, but it conveys the idea.
Hans and Taco, can something like this be added to the core? If so, I will try to make this macro more robust (correct inheritence, etc.)
Here is a more robust version. I use \??sf as a namespace for subformulas. I do not think that this is used anywhere else. Aditya
