any licence which authorises the holder to act as a member of the flight crew of an aircraft and is granted:
(a) under the law of a Contracting State other than the United Kingdom but which is not a JAA licence...is, unless the CAA gives a direction to the contrary, deemed to be a licence rendered valid under this Order.

I disagree. The French PPL does not authorise the holder to fly a microlight, so the CAA can hardly override that. It would be different if the Contracting State did not specifically exclude microlights from PPL privileges.
In the event of an incident, the foreign licence would need to be verified with the issuing state and the microlight exclusion would come to light.
