Quilombo, sorry, but you are speaking about other thing, tthis is called "Documento de viaje", if you hold it in hands it says exactly this, its for refugiados/apatridos etc. If someone was acknowledged as refugee by CONARE, they just bring it I believe.
Pasporte for foreigners looks like passport and says passport, it is different tramite.
It is for foreigners who are residents, and can't obtain a passport easy way, no consulate near for ex.This is theory, but on practice provincial registros have no idea
