Hello

We are translating all official GNU Emacs documentation into Spanish
for a future i18n/l10n of the program.

We are very advanced translating the Org-mode texi manual, but
there is a @-command which we had never heard: @tsubheading.

This command is not documented in the Texinfo manual and is causing
problems in the provisional generation with texinfo-format-buffer, because
it is not recognized.

Please, can you help with some directions?

Regards
