Sorry, I think I may have missed the point of your report. org-babel
tangling and export procedures should of course proceed without problems
in the presence of an unknown language block. Could you provide an
example file in which the error occurs? Are you sure that all blocks in
the file are started/terminated correctly? I tried the test file below
containing your emacs-shell block and, for me, it tangles correctly
(just the two emacs lisp blocks), and exports to HTML (all three
blocks), and org-babel-load-file works on it (the two variables have
their values set). Does it work for you?
