Problem with references to babel source blocks (possible bug).

[Emmanuel Charpentier <emanuel.charpentier@gmail.com>]

I wish to be able to reference (i. e cross-references, lists) both some
tables or figures AND the code producing the objects.

To this effect, I added (distinct) #+caption:s to the source blocks AND
to the results, adorned with (distinct) org-ref's labels. An example ( 
Min-Ref.org) is included in this Google Drive directory*: 
https://drive.google.com/drive/folders/1T6N_-WwphlnL2mB4f6BgX0u1K5mLnz4i?usp=sharing
.

The comparison of this source, the LaTeX code obtained by org-latex
export-to latex (Min-Ref.tex) and the resultant PDF (Min-Ref exported
by org-latex-export-to-pdf.pdf) show that the labels attributed to
source blocks are mislabeled as figures. Furthermore, while the org
source requests a list of figure, a list of table and a list of
listings (in that order), the list of figures appears *after* the list
of tables.

I am tempted to conclude that there is some confusion between figures
and listings. Further attempts tend to show that the problem may live n
the core org's code, rather than any specific exporter :

The ODT "native" exporter (org-odt-export-to-odt) is much less capable,
as shown in Min-Ref exported by org-odt-export-to-odt.odt.

Attempts to export via Pandoc to PDF (Min-Ref exported by org-pandoc-
export-to-latex-pdf.pdf), ODT (Min-Ref exported by org-pandoc-export-
to-odt.odt) and DOCX (Min-Ref.docx) show that these exporters may need
some specific configurations in order to be even vaguely usable.

Previous trials, using #+names: rather than org-ref's labels, gave
similar failures. If needed, I can reproduce these trials.

So I have a couple questions :

1) Is the confusion of source blocks and figures a bug, or do I miss a
subtle point ?

2) Is there some introductory material to the care and feeding of ox-
pandoc demonstrating the use of this exporter's options to enable the
addition of the needed features (figure inclusion, tables of tables /
figures / listings, etc...) ? The "manual" available as a README is way
too terse to be usable without diving in the source code and pandoc's
documentation.

Sincerely,

convinced me that the list manager rejects at least the messages
containing some attachments (docx ? dot ?) ; I'm a little bit fed up
with this...
