I may conclude, I use indicate, the SKOS artifacts are not sufficient for my
use case.
The post I made is to validate this.

I do thing though it is also and RDFS/OWL issue.
As indicated below, the OWL semantics easily allow to break any language
specific modeling.
So specifying properties like prefLabel-LANGUAGE always will need
proprietary code to validate.

It may be interesting for SKOS to promote this use case to OWL 2.

You are likely to have to create a prefLabel-LANGUAGE for each of your
desired languages to get around it, trouble is though, that you can't
get around the prefLabel cardinality if you derive these from it, so
you would have to find another way. OWL doesn't care about literals
really, it is more focused on ensuring that subjects and predicates
are used "accurately", where accurately is decided by the ontology
designer. Is there any real advantage to using prefLabel instead of a
whole lot of alternates in your case anyway?
