Thanks Jeong,
I was aware of this. While there is no solution that adds vertical lines into
matrices, one can juxtapose two (or more) of them with
properly chosen delimiters, like so:
\definemathmatrix
[bvmatrix]
[left={\left(\,},right={\ \right\vert}]
\definemathmatrix
[rbmatrix]
[left={\left.\,},right={\,\right)}]
\starttext
\startformula
\startbvmatrix
\NC 0 \NC 0\NC 0 \NR
\NC 1 \NC 0\NC 1 \NR
\stopbvmatrix
\startrbmatrix
\NC 0 \NR
\NC 1 \NR
\stoprbmatrix
\stopformula
\stoptext
