Again it's an ICAO standard, and from the SAFA inspections manual:
With regard to pilot licensing three different scenarios can be identified.

Case 1
State of Licensing issuance is the same as the State of Registry
Instructions
Check that pilot licence is issued i.a.w. the applicable ICAO Standards of Annex 1.

AFAIK the ability to alternate types is an FAA standard and not an ICAO standard so legally ambiguous outside the USA.... Depends how deep into the inspection they get but worthy of note?!
