I' m trying to follow the examples at this page
http://orgmode.org/manual/HTML-doctypes.html#HTML-doctypes
to transform
#+BEGIN_ASIDE
Lorem ipsum
#+END_ASIDE
in
but it doesn't work, I still get
Lorem ipsum
I tried to both include the directive in the "group" in the project
definition AND using
#+HTML_HTML5_FANCY: t
in level-0.org
What am I missing ?
