Hmmm. Interesting. This is not my impression of the use of hierarchy.
Having re-read SDN.801 I can see it isn't clear what the purpose of
hierarchy is. [Having said that, I've yet to meet anything that is clear
in SDN.801 :) ]
With your approach, how do I know if a label with classification value
of 27 dominates (or not) a label with classification value of 5?
Leaving classifications aside, I can still see a reason for hierarchy
attribute on categories. If I have a hierarchic category named "Impact"
with values "HIGH", "NORMAL" and "LOW" how do I present these to the
user appropriately? Do we sya that "convention" is that they are
presented in the order in which they are listed in the SPIF?
I prefer formality to convention. NB I'm only proposing this as an
optional attribute.

Piers

Note that classification hierarchy in SPIFs is only for display purposes
(ordering of classifications in UI menus and such). It should not used
in evaluation of the ACDF.
