I would like to get them interpreted as raw LaTeX code in such way 
MathJax can reinterpret them as you said.

In my case, the code is not even wrapped into org-src-container class, 
it just does not appear at all.

Actually, I just want to get the LaTeX code translated into raw code. As 
I wrote, there is one solution, pretty easy to implement and may be used 
by most of the org users : write raw LaTeX inside org document and use 
MathJax for example, to interpret it in a convenient way. It is going to 
work for both exporter html and latex. The point here is that using raw 
LaTeX code makes me lose the syntax highlighting which is really useful 
for debugging long LaTeX equation.

Cheers,
Xavier
