[NTG-context] Myway on using mathalign

Hi Aditya, I read you MyWay document on using \startalign and I was interested in section 4.2 numbering subformula's Everything works fine as stated in your nice document. One thing I want to do with a set of subformula's is to reference the main formula but still subnumbering the equations like \starttext \incrementnumber[formula] \placesubformula \startformula \startalign \NC div \vec{E} \NC = \epsilon_{0}^{-1} \rho \NR[eqn1:A][a] \NC rot \vec{E} \NC = 0 \NR \NC div \vec{B} \NC = 0 \NR[eqn1:B][b] \NC rot \vec{B} \NC = \mu_{0} \vec{j} \NR \stopalign \stopformula See *\in[eqn1] *for the static Maxwell equations, where we are going to examine \in[eqn1:A] a bit further .... \stoptext Hope you can help Thanks Wim
