Unfortunately this is not what jsMath expects. We get this in the html file (see attached files for full source) ---

This is what we want $$ \label{eq:1} y = ax + b $$

This is what we get

\label{eq:1} y = ax + b

-- What we need to do is to replace \begin{equation} ... \end{equation} with $$ ... $$ in the HTML export. Any idea of how to do this?
