Subject: [tex4ht] fyi, error with mathml switch, question posted

this is just FYI;

I think there is a problem with tex4ht when compiling a small
example using mathml mode.

Easier to post this question on tex exchange (screen shots).
But thought some here might be interested to know about it.

{\end{BMAT}\right)}
\begin{pmatrix}

C & D
\end{pmatrix}
\egroup
\end{multline*}
