To dive a rebreather, you must be certified on the gas you are breathing. And it must be CE approved.
I dived in southern France with my MK-15 in Oct-2000. No one asked me if it was CE-approved, so may be things have changed now...
Matt, send Simon (IANTD-UK) an email. A few months ago, he sent out a notice about a recent agreement about cross-recognition between CMAS and IANTD certs.
