Dear all,
it is not clear to me how to render a menclose element, except for the
case when notation is radical. Given the examples in the last draft it
seems that for notation="longdiv" it is just a matter of prepending a
) to the content of menclose, while for notation="actuarial" one has to
draw the upper-right edges of a box around the content (thought the
example uses a msub element whose behaviour is not the standard one).
Am I missing something?
