I'm a bit wary of quoting individual regulations verbatim as a means of explanation  - in some cases regulations can only be read correctly in their wider context (including their position in the regulations, relationship with other regulations that might modify or provide exemptions, and general definitions).

For example read:

411.3.4 Additional Requirements for circuits with luminaires

Within domestic (household) premises, additional protection by an RCD with a rated residual operating current not exceeding 30mA shall be provided for AC final circuits supplying luminaires."

Now ask yourself if that includes 12V SELV lighting running from a conventional transformer. From the words provided you could only conclude that it does - which would be completely wrong. Only by realizing that the regulation is in section 411 which only applies to ADS and SELV lighting comes under the mutually exclusive section 414 can it be understood correctly.

Certainly refer to regulation numbers - which should be taken by the initiated as a starting point - and by all means add a helpful 'plain English' explanation or summary to help the intended audience, but quoting individual regs out of context I fear risks giving the impression of definitive accuracy that isn't really there.
