Dear Edgar,

Thanks for your help on the export of bibliography for docx or odt. I am
going to persist in trying to succeed it.

About proof.sty, really there is not  the least problem from org-mode to
latex, everything  is smoothly  exported and the  final pdf  document is
really     nice     (with     the     really     pretty     smfart.class
[[http://smf4.emath.fr/Publications/Formats/]] that I advice.)

No,  my problem  is only  with the  export of  these proof  to odt,  and
Authorea fails  also (that is  the main reason  why I gave  up Authorea,
which seems  to me  being a  nice project, but  not complete  enough and
therefore unfortunately  useless for me). The  only reasonable solutions
seems to me the png export from a succeeding org export to an odt file.

Best wishes,
