There is this rule
term-1 <- sumti / ( !gek (tag / FA-clause free*) (sumti / KU-clause? free*) ) / termset / NA-clause KU-clause free*
I don't have a firm grasp of formal grammars, so correct me if I am wrong.
1. This rule is relevant.
2. If we make the KU-clause mandatory, instead of optional, my mental grammar is realized.
term-1 <- sumti / ( !gek (tag / FA-clause free*) (sumti / KU-clause free*) ) / termset / NA-clause KU-clause free*
3. It would contradict the CLL, though.
