Indeed, this is much better! Thank you!
I recommend to include this as a patch in ConTeXt.
However: Testing never stops ;-) I have the following MWE:
\definemathmatrix[pmatrix][left={\left(},right={\right)}]
\math{
\startpmatrix
\NC A \NC B \NR
\NC C \NC D \NR
\stoppmatrix}
This (including your suggested fix) results in the following structure tree:
<document>
|-<math>
| '-<mrow>
| '-<mrow>
| '-<mfenced>
| '-<mrow>
'-<math>
'-<mtable>
|-<mtr>
| |-<mtd>
| | '-<math>
| | '-<mrow>
| | '-<mi>
| | '-"A"
| '-<mtd>
| '-<math>
| '-<mrow>
| '-<mi>
| '-"B"
'-<mtr>
|-<mtd>
| '-<math>
| '-<mrow>
| '-<mi>
| '-"C"
'-<mtd>
'-<math>
'-<mrow>
'-<mi>
'-"D"
I think that the <mtable> should be located within the <mfenced>, shouldn't
it?
Cheers,
Christoph
