$sm fields inside $match — allowed by example, forbidden by Note 1 ?

[DenisBiondic]

Section "Match of Elements in Lists" states in Note 1:

"If the comparisons inside an $match clause contains expressions that are not pointing to the list under consideration, an error shall be returned."

However, the TechnicalData example in "Examples for Grammar and JSON Schema" includes $sm#idShort inside $match:

$and(
$match(
$sm#idShort $eq "TechnicalData",
$sme.ProductClassifications[].ProductClassId#value $eq "27-37-09-05"
),
...
)

$sm#idShort is a scalar submodel-level field — it does not point to any list. Per Note 1 this should be an error, but the example treats it as valid.

Question: Are scalar fields (like $sm#idShort) that don't reference any list intentionally allowed inside $match as contextual filters? Or should the example use $and instead of $match for the $sm#idShort condition?

I think this issue is addressed to Part 2 Query Language: moved

I think the Note needs to be reformulated. The "list" under consideration in this example is the submodel itself and all its elements . We probably should add a wrong example for what would not be allowed.
