When I start it as 'emacs -Q <file>.dtx‘ it opens the requested file in
DocTeX mode. 

Next I load 'outline-minor-mode‘.  If I than run the command
'outline-hide-body‘ I’d expect to be presented with the various
\section, \subsection, … commands.  But this does not happen. 

Instead the first meta comment, the documentclass command and the
document environment are displayed, see the text below.  Any other
sectioning command is hidden.

Thanks in advance.
