A vocab won't build as expected when concepts are linked by skos:broader/skos:narrower to top concepts but don't have a skos:inScheme statement. But there will be no validation error. Thus, we should check whether all concepts are linked to the concept scheme either with skos:inScheme or skos:topConceptOf or the inverse skos:hasTopConcept.
