DMN13 — Rule 51.c doesn't support FEEL syntax of list with squary brackets as shown on page 122

on page 122 in table 43 in row 2 and 3: "e1 in [e2, e3, ...]"
on page 109 grammar rule 51.c: expression "in" positive unary test
on page 109 grammar rule 51.c: expression "in" "(" positive unary tests ")"

The syntax with square brackets is not allowed by the grammar rules 51.c. Either table 43 or grammar definition should be changed.

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.
