ConTeXt does support that (see above); but aligning at the + sign makes
sense only for specific types of equations. In general, using \quad is
considered good typography. (Imagine what would happen if the first term
in one of the equations was very big).

Thank you. It is perfect now. I think this solution deserve appearing in
your MyWay manual. In fact, it deserves to be supported directly in MKIV.

Thanks, but your output is not the same as mine. The comment "by
Equation 2" must be right aligned exactly where formula number is. Also
I don't like manual alignment like \quad. AMS-TEX provide commands for
automatic alignment. It would be nice if context supports that too.

This has 4 columns. You do not get an error message because you use \cr
