When making this decision in PWG, please also consider that Canon uses the term "Indian Legal" or "Legal(India)" to distinguish it from the US region’s Legal size, since Canon printer supports both region's Legal paper sizes (India and US) together. That naming would be easier for user to distinguish.”

OK, let's discuss this at next week's IPP WG concall to finalize what actually gets registered.

Given our current document schedule, I would say no earlier than the second half 2026.  That said, the example localized names for PWG media size keywords are non-normative so even once we put out an MSN update there really isn't a way to enforce or standardize such localization...
