Hi all,

   We can write LaTex directly in org-mode without put it in a SRC block. When the code is exported, the latex syntax will be handled correctly to html or pdf. That's very nice part of org mode. However, if we don't put the latex code into a SRC block, the latex syntax is not correctly highlighted (in the code attached below, the first equation is not highlighted). Another benefit of putting the latex code into SRC block is that we can easily switch to the latex mode to edit the code snippet using C-c ' and in the latex mode, we can use some full-fleged latex package like auctex. However, the latex code in the SRC block is ignored when exported to html. For example, when I exported the following to html, the first equation shows up in the html but the second seconed does not.  Any way to make the html exporter to generated the second equation too without taking away the BEGIN_SRC/END_SRC? What's the best practice to write latex in org-mode. Thanks. 

\begin{equation}

    \label{eq:test}

    Bx=b

\end{equation}

#+BEGIN_SRC latex 

  \begin{equation}

    \label{eq:test}

    Ax=b

  \end{equation}

#+END_SRC
