DMNFTF — "Should not conflict with FEEL Syntax"

Table entries "SHOULD NOT conflict with FEEL syntax" (4 places). OK, I know why you're saying this, but that "SHOULD NOT" is such a weak statement as to be useless. I suggest making it part of the conformance criteria: "At Conformance level 1, there is no restriction on table entries, which are not interpreted. However, at conformance levels 2 or 3, table entries SHALL comply with FEEL syntax".

Add an expression language URI to indicate that expressions are not meant to be machine interpreted; edit text to introduce the URI and clarify its recommended usage.
