Question: Is it possible to tag displayed equations (inside
\stopformulawith an arbitrary tag in ConTeXt?
With LaTeX I can do
with the result
I think that previously one could in ConTeXt write
to have the equation tagged with an A, but now I get, with a recent standalone,
I would like to have the tag to the right as in the LaTeX example, and it is fine if it is not possible to refer to the equation later. Just to make the question clearer, I do not want to number the equations with characters A, B, ..., but really want to be able to set an arbitrary tag. Sorry for not being perfectly clear about this in the first version of the question.
My efforts so far is that I have looked for something that could fit in setup-en.pdf. I also made a search in the source, and the file
strc-mat.mkiv looked interesting, but I could not find out if it had what I am looking for.
