Dan,

Using the W3C utility for extracting triples from HTML+RDFa documents 
[1], I don't the see the issue I raised, so yes, it could actually be a 
glitch in a URIBurner heuristic, which I'll look into.

Excerpt in Turtle that proves the original source isn't problematic re., 
object of rdfs:subClassOf relation:

<http://schema.org/Vehicle>
<http://www.w3.org/1999/02/22-rdf-syntax-ns#type> 
<http://www.w3.org/2000/01/rdf-schema#Class> ;
<http://www.w3.org/2000/01/rdf-schema#label> "Vehicle";
<http://www.w3.org/2000/01/rdf-schema#comment> "A vehicle.";
<http://www.w3.org/2000/01/rdf-schema#subClassOf> 
<http://schema.org/Product> .

[1] http://bit.ly/1fYuk3y -- W3C (as opposed to URIBurner) extraction of 
RDFa from <http://schema.org/docs/schema_org_rdfa.html> .
