I was also able to rework the antlr to support all of the following

RECORD
STRING1 test;
SET OF UTF8 fieldAllset {DEFAULT (ALL)};
SET OF UTF8 field2set {DEFAULT (['test1','test2'])};
SET OF UTF8 field3set {DEFAULT ([''])};
SET OF UTF8 field4set {DEFAULT (['test'])};
STRING2 test;
END;

Test failures seem unrelated to proposed changes.

Minor: formatting differs here, and might want to remove these commented out lines.
