When a #+begin_foo token is encountered by the LaTeX ;; exporter, it is expanded into \begin{foo}. The text inside the ;; environment is not protected, as text inside environments generally ;; is. When #+begin_foo is encountered by the html exporter, a div ;; with class foo is inserted into the HTML file. It is up to the ;; user to add this class to his or her stylesheet if this div is to ;; mean anything.
