This has got me so curious that I've actually looked up the EASA regulation.

(a) Content. The item number shown shall always be printed in association with the item heading. Items I to XI are the “permanent” items and items XII to XIV are the “variable” items which may appear on a separate or detachable part of the main form. Any separate or detachable part shall be clearly identifiable as part of the licence.

(VII) signature of holder;
(VIII) competent authority and, where necessary, conditions under which the licence was issued;

(XIII) remarks: i.e. special endorsements relating to limitations and endorsements for privileges, including

deletions to the form will be clearly authorised by the competent authority.
(c) Language. Licences shall be written in the national language(s) and in English and such other languages as the
competent authority deems appropriate.
Nowhere does it say that everything has to be shoehorned onto one piece of A4.
It actually says that an item such as the ratings page can be a separate item, as long as it is clearly identified.
Basically the CAA have chosen to interpret the regulations in a completely cocked-up manner for reasons known only unto themselves!!! I would say it beggars belief, but then it is the CAA we're talking about!
