I thought about it.  But, as I said, I'm going to have two backends,
one for LaTeX, one for HTML.  WOuld it be possible to have e.g.

#+ATTR_TEST

working for both?

(Anyway, options after #+BEGIN_MYBLOCK would be a bit nicer, since the
user would not have to type /that/ much.)

Thanks, I'll look into this!

I tried to look for math-block in ox-latex.el, but did not find it.  I
have Org-mode from Elpa, org-version gives:

Org-mode version 8.2.5f
(8.2.5f-elpa @ /home/marcin/.emacs.d/elpa/org-20140116/)

Should I upgrade?
