Isn't any <orthography> just a set of rules, put into the identifiable 
set of paper books, electronic documents, etc.?
People never actually use 100% pure <orthography Mk.X>. The deviations 
may form their own identifiable ruleset, and so on.

Isn't it missing the mark completely? The edition/translations has 
responsibles, publishing attributes, ratification date, whatever.
There may be several re-issues of the same standard. How do you account 
for those in the scheme you cite?
