I think that's what Mr.(Dr.?) Neves asked for; 
but I will let him clarify himself the periods/orthographies he wishes to distinguish.
(If I can add a note here, I want to note that it's my understanding that anyone and not just Jose can apply for an additional subtag for Portuguese as needed;
the prefix could be just pt;
or it could be something like pt-PT ; but I do not know how much support there would be for the latter.)

Just a quick question regarding the dates; is the info (in English) at the following URL accurate for all dates/countries:
Thanks for clarifying this.

Hi, after reading this and Addison's post,
I have decided to not push one order or another, 
but do hope we can get decent names for these short subtags (though we can no longer get these for language subtags)

Thanks Antonio very much for this.
I do feel some letters may be needed because of different dates of implementation in Brazil and Portugal.
That's a personal opinion.
