Message text written by John Cowan > And contrariwise: if you cannot specify hardwired constraints, you may break rigid downstream systems that *know* that there are 28, 30, or 31 days in a Gregorian month: element month { repeat 28 { day } | repeat 30 31 { day } } <<<< John, I'm not saying exclude #'s - just the default should encourage people to build software that works regardless. Notice the +, * and limit=n mechanism allows you cover off all value combos that min=, max= does - BUT - forces them to think open - so I'd design something : year [ month(month_number, month_days) ] as a memory structure I can just assert facts into, rather than hardwiring limits into a static array (did I mention arrays are another of my pet peeves?). BTW the month is a good example since Hegira calendars have 29 or 30 day months depending on the phase of the moon.... ; -) Cheers, DW.
