Technically the NPPL(M) has the same restriction as the SSEA version when it comes to operating in Europe however; microlights have been given permission in the past to cross borders and there is a general acceptance of microlight licences around Europe. Some States don't even require a licence to fly a microlight as did the UK back in the 70s.
To add to the confusion the PPL SLMG used to be an ICAO licence but now that its an NPPL it may not be (40 hours required to be ICAO compliant).
The NPPL was introduced by one person in the CAA who wanted to impress the chairman; it got him promoted, and produced the biggest load of Beaurocratic Garbage in aviation history. All that was required was a two tier medical system, that allready existed for microlights, and no ANO amendments!
