How should the ICU calendars handle values of eraYear
and era
that are "out-of-bounds". For example, if an era lasts ten years, does eraYear: 15
mean 5 years into the next era? For the gregorian calendar, does {era: 'ce', eraYear: 0}
mean 1 BCE?
This does not affect the ISO calendar, which does not support eras, and therefore will not lead to any changes in the stage3 "frozen" spec text. It does, at the moment, affect the polyfill.
