[O] [Bug] local variables definition at beginning of file is ignored

[Viktor Rosenfeld]

Hi everybody,

in http://thread.gmane.org/gmane.emacs.orgmode/47043 I've posted two
examples of local file definitions at the top of an org file which are
silently ignored for seemingly unrelated parts in the org file. The
definitions work if they are put at the end of the org file. 

This inconsistency is a bug, isn't it? Also, are local variables
documented somewhere? I couldn't find anything in the manual.

Cheers,
Viktor
