reading 714.1 scope, domestic garden lighting that is not attached to the outside of the building is within scope of 714.

you then have to decide whether the public have access to the garden, in which case an RCD is required.

411.3.4 states "Within domestic (household) premises..." (my bold), so unattached garden lighting falls outside the scope of this reg and if fed by a dedicated circuit does not require RCD protection. In fact attached lighting outside doesn't need it either, if fed from a dedicated circuit. This seems a bit odd, and could be worded better.
