Half-Elf / Orc Ethnicities in Bastards of Golarion

[PaperStSoapCo]

Are the various Half-Elf/Orc Ethnicities listed in Bastards of Golarion legal for play? Additional resources states that racial traits are legal if the character matches the ethnicity but does not clearly state those ethnicities are legal. In contrast, Human ethnicities are listed out as being legal in the Inner Sea World Guide entry of Additional Resources.

The alternate racial traits are in fact the entirety of the ethnicities, as you do not get any of the listed languages for free.
