I suppose they haven't yet added these models to the document. The quick reference guide and installation guide do mention output power, gain and approved antennas but these seem to be FCC and ISED related.
Yes, that's a possible standing. But FCC and IETF require a validation of RF equipment especially on outdoor installations.
So the vendor has to define and validate the approved equipment.
It´s like all the other APs defined in the sheet, but the new AP76xx are missing there.
