Responding to a recent report on -general [1] I found a markup bug in the primary key description under create table. 0001 fixes this.
The complaint itself was about using "column constraint" as a descriptive label in a syntax area when "column constraint" is an actual defined syntax label. 0002 adds the word "variant" to the six places "(table/column constraint)" is used in this manner.
The more you look (not having production dark mode in the core build is a bit annoying)...v2 attached after re-reading the original thread and looking around a bit more.
Unique had the same sgml markup error as primary key.
P.S. Reviewing this we are inconsistent as to where we use "optional" markup versus just literal [ ]. Even among these three locations there are variances - and simply literals used for optional meaning brackets.
