Correct me if I'm wrong, but I think I hear Tom saying the words from
SKOS B.2.4 are problematic for Antoine's suggested triple:

skosxl:Label rdfs:subClassOf frsad:Nomen .

Given B.2.4, I'm having trouble believing this example doesn't conflate
two Nomens:

ex:nomen1 a frsad:Nomen ; # could be inferred from skosxl:Label
	a skosxl:Label ;
	frsad:soundLabel ex:genericresource1 ; # content-negotiable for
audio/* media-types
	skosxl:literalForm "Fire Alarm" .

frsad:soundLabel a owl:ObjectProperty ;
	rdfs:domain frsad:Nomen ;
	rdfs:range owl:Thing .

Should we start hoping that SKOS B.2.4 can be relaxed so frsad:Nomen
doesn't become a specialized niche?
