I think this is quite elegant...

With what you say below, we then have 3 different solutions (at least) for new
environments:

- the one above, where you add a new environment definition (but, then, it's
kind of private for your own files; difficult to share)

- the Org special blocks, ancient way, which you've fixed

#+begin_myenv{2cm}
Contents...
#+end_myenv

- the Org special blocks, new way, with the OPTIONS

#+LaTeX_ATTR: :options {2cm}
#+begin_myenv{2cm}
Contents...
#+end_myenv

Now, a big question: outside the fact that some such "standards" (like
"texpos1") would have to be added IMHO as default Beamer environments, what

I think normal, then, to wanna get that same behavior in the LaTeX backend.
How to do that?  I'm a bit puzzled by the differences to get some similar
results...

- In LaTeX, you have the inline tasks which can be used to insert blocks, but
right?

- In Beamer, we have both?  And, for whatever reason (which must escape me),
we tend to prefer the "ignoreheading" for closing a block.

In my latest slides, I've been quite disturbed by how much "pure LaTeX" I've
finally inserted in my slides, for inserting TikZ nodes to render boxes. I had
the impression to write LaTeX inside an Org file; and that's not the right
approach:

- too much LaTeX tag overload,

- no HTML equivalent for the contents of my boxes -- while, as presented here
above for the "textpos", even in HTML, it'd be quite nice.

- no Org syntax usable: inside my boxes (TikZ nodes), I had to use \textbf for
bold, not the stars...

Now, there are, once again, other extra solutions: MACRO and Org Babel calls.

Too much solutions...

OK, thanks!
