Summary
AlternativeNumberstring element to the v1.1 draft schema, placed alongside the existingNumberelement.Why
Marvel and DC (and some other publishers) occasionally publish issues with a legacy or alternate numbering scheme in addition to the primary issue number (e.g. a title relaunches at
#1while also carrying over its "legacy" numbering from a prior volume).AlternativeNumbergives metadata consumers a place to record that secondary number without overloading theNumberelement.Closes #67
