`org-e-odt-convert-process' can take any document that is in

OUTPUT-FMT-LIST.  A document converted to OUTPUT-FMT will have
OUTPUT-FILE-EXTENSION as the file name extension.  OUTPUT-FMT

- It is used as the value of \"%f\" specifier in

EXTRA-OPTIONS is used as the value of \"%x\" specifier in

DOCUMENT-CLASS is used to group a set of file formats in
INPUT-FMT-LIST in to a single class.

Note that this variable inherently captures how LibreOffice based
converters work.  LibreOffice maps documents of various formats
to classes like Text, Web, Spreadsheet, Presentation etc and
allow document of a given class (irrespective of it's source
format) to be converted to any of the export formats associated
with that class.

configuration."
