DMN17 — Inconsistency DMNv1.2 dropping [a]=a and get entries example

Since DMNv1.2 the spec dropped the equivalence of:

[a] = a

because it does not apply to the statement that

a singleton list L, when used in an expression where a list is not expected, behaves as if L[1] is written.

So the expression

[a] = a

on DMNv1.2 is expected to return false.

However, in section 10.3.2.6 Context of the spec, it provides the following statement for the get entries function:

To retrieve a list of key,value pairs from a context m, the following built-in function may be used: get entries(m).
For example, the following is true:

get entries({key 1 : "value 1 "})[key="key 1 "].value = "value 1 "

BUT

get entries({key1 : "value1"})[key="key1"].value = "value1"

  by substitution:

[ { key : "key1", value : "value1" } ][key="key1"].value = "value1"
[ { key : "key1", value : "value1" } ].value = "value1"
[ "value1" ] = "value1"

according to DMNv1.2 should be false

By the same principle that the DMNv1.2 for the following literal expression:

[123] = 123

on DMNv1.2 is expected to be false
