IMHO, natural-language (English, French, or whatever) descriptions
are generally preferred to formal ones, as they are intelligible
to more people and generally "live" longer.
A document that says
The MagicDate format is as follows:
yyyywwd, where yyyy is a zero-padded Gregorian year number,
ww is a 2-digit week, and d is the day of the week.
Week 01 of a year is the week containing January 4.
Day 0 is Sunday, day 6 is Saturday.
does very nicely. Then you make it retrievable at
then declare the notation in your DTDs as
<!NOTATION MagicDate SYSTEM "http://your.domain/defs/MagicDate.txt">
