1.4.1.2 (Modified BNF Syntax) does not mention {} explicitly and http://www.lispworks.com/documentation/HyperSpec/Body/01_daba.htm gives the incorrect example (x [[{A}¹ | {B}¹ | C]] y) which should be (x [[A¹ | B¹ | C]] y) so the situation is a bit confusing. See https://irclog.tymoon.eu/libera/%23commonlisp?around=1677680808#1677680808.

A WSCL issue for adding an explicit discussion of {} should be create, but I don't have the time right now.
