Hi,
There was some discussion of tag hierarchies in this thread:
http://thread.gmane.org/gmane.emacs.orgmode/31882
It was largely inconclusive, except that it would be hard to
implement. Noone took the ball and ran with it, but then noone came up
with a strong use case or specification, either. Anyway, I recommend a
look at that thread before continuing it here.
Yours,
Christian
