dired local ignore file extensions

[Sivaram Neelakantan]

While working on latex beamer, I'd like to ignore additional file
extensions.  I created a .dired_local.el  file with the following
entries,

((dired-mode
  (completion-ignored-extensions . ".out")
  (completion-ignored-extensions . ".vrb")
  (dired-omit-mode . t)))

This doesn't seem to ignore the files ending with the above extensions
though omit-mode becomes enabled.

I created the first ignored entry using M-x add-dir-local-variable and
repeated the generated form.  How do I get to ignore *additional* file
extensions apart from what completion-ignored-extensions already
generates that is directory specific?
