Hi Vikas,

I now use TikZ to do that. I have the impression it is easier. Though, I have
the real impression of writing LaTeX inside an Org buffer... which I dislike.
I'd like to write text as text, and still get the ability to convert that to
HTML, for review, even if the layout wouldn't be (at all) the same.

You normally could use such a block (the old "org-special-blocks", now
integrated in Org 8 -- thanks Nicolas):
--8<---------------cut here---------------start------------->8---
#+begin_textblock
Contents
#+end_textblock
--8<---------------cut here---------------end--------------->8---

Though, the problem stays the same with what I think is the right way to do
it...
See how Org gets converted to LaTeX:
--8<---------------cut here---------------start------------->8---
#+begin_myenvironment \begin{myenvironment}
Test of a new Test of a new
environment. environment.
#+end_myenvironment \end{myenvironment}
--8<---------------cut here---------------end--------------->8---
That's OK. But the environment had no parameters.
--8<---------------cut here---------------start------------->8---
#+begin_myenvironment{3} \#+begin\_myenvironment\{3\}
Test of a new Test of a new
environment. environment.
#+end_myenvironment \#+end\_myenvironment
--8<---------------cut here---------------end--------------->8---
That's completely invalid LaTeX.
--8<---------------cut here---------------start------------->8---
#+begin_myenvironment {3} \begin{myenvironment}
Test of a new Test of a new
environment. environment.
#+end_myenvironment \end{myenvironment}
--8<---------------cut here---------------end--------------->8---
That's valid LaTeX, but the arguments of the environment have been ignored!
IIRC, that's how we did before, with the original `org-special-blocks' file.

I've no idea. I wonder as well how we do this.
Best regards,
