Eason.., fair enough!

In Euro-land - and Oz/NZ, for that matter - our 'certificates' are 'licences' onto which may be added ratings such instructor, instrument, class or type ratings eg single engine <5700kg etc etc etc.
An ATPL is an Airline Transport Pilot Licence, that's all.
The term 'Frozen ATPL' only tends to be used in Euro-land and is nothing more than a Commercial Pilot Licence holder with instrument rating who happens to have also passed all of his or her ATPL exams.
In the UK there is no requirement for a further flight test to be issued with an ATPL. It can be issued on application once the required experience & age limits are met.
