  schema:comment """Regarding the use of `schema:domainIncludes`
and `schema:rangeIncludes` in this ontology:
Looking at the definitions for the RDFS version
of the two, `rdfs:domain` and `rdfs:range`:
* https://www.w3.org/TR/rdf-schema/#ch_domain
* https://www.w3.org/TR/rdf-schema/#ch_range
and as described in this StackOverflow answer:
<https://stackoverflow.com/a/74782257/586229>,
multiple objects for the two RDFS properties mean,
that *all of them* apply, simultaneously,
not *one of them*.
You may think of this as an `AND` coupling.
We want the *one of them* meaning though (`OR`).
The `schema:*` properties give us just that."""@en ;
