It would be nice if the constructed heading could have references to the component LCSH concepts. It seems unfortunate that skos:OrderedCollection and skos:Concept are disjoint. If they weren't, then the component concepts could be listed in a skos:memberList. Barring that, I could imagine a new SKOS property like this to expression the coordination: skos:coordinates a owl:ObjectProperty ; rdfs:domain skos:Concept ; rdfs:range skos:OrderedCollection .
