DMN13 — Missing FEEL semantic mapping for grammar rule 2.i - simple positive unary test

For simple positive unary test(s) there are extra entry points in the FEEL grammar. Therefore why do we need simple positive unary test in grammar rule 2.i. What is the semantic mapping?

RTF 1.3 is ending

Thank you for reporting the issue; it is likely valid but unfortunately the DMN 1.3 revision task force ran out of time before a member was able to resolve it. The issue will be deferred to the next revision task force.
