I looked at ITU T.416, which I believe is equivalent to ISO 8613-6 but
has the advantage of not costing me USD 179, and it looks very similar
to ISO 6429 (ECMA-48, formerly ANSI X3.64) with regard to the things we
are talking about: setting text display properties such as bold and
italics by means of escape sequences.
 
Can you explain how ISO 8613-6 differs from ISO 6429 for what we are
doing, and if it does not, why we should not simply refer to the more
familiar 6429?
