We need to considering doing the following: 1. Apply a similar note to other types. 2. For duration, provide conformance criteria for other fields than year and second. The lex value "P99999999999999999999999999M" is currently allowed, but I don't think we want to require mininum conforming processors to support it when they are allowed not to support "P10000Y". For #1, the solution is abviously to apply the note we have for duration to dateTime, time, date, gYear, and gYearMonth. For #2, there are 2 ways to solve it: either we specify limits for each field, or we specify limits on the equivalent (month,second) values. That is, Option A: All minimum conforming processor must support duration values (y,m,d,h,mm,ss): 1) y <= 9999 2) m <= 11 3) d <= 30 4) h < 24 5) mm < 60 6) ss < 60 7) ss with at most 3 fractional digits Option B: All minimum conforming processor must support duration values (y,m,d,h,mm,ss): a. abs(y*12+m) < 120000 b. abs(d*24*3600+h*3600+mm*60+ss) < 31*24*3600 c. ss with at most 3 fractional digits
