DOCBOOK-APPS: editing XML in outline mode??

["Robert P. J. Day" <rpjday@mindspring.com>]

  for the longest time, i've designed manuals using emacs outline
mode, given the invaluable ability to expand and collapse any part
of the document.

  given that i'm just about to start learning the psgml package
to use with emacs, can i still set it up to use outline mode
while retaining psgml functionality?
