You said:
    If you're seeing something in what I wrote that implies that rdf:Property is a subclass of rdfs:Class, please point it out to me.

The thing that I saw was your definition of rdfs:Class as being the set of y such that
    x  rdf:type  y
from that and
    z  rdf:type  rdfs:Property
it follows that
    rdfs:Property  subClassOf  rdfs:Class

If RDF-MT doesn't agree, then RDF-MT is wrong (or your definition of rdfs:Class is wrong).

That stirs up some vague recollections of Pat Hayes' statements that RDF-MT doesn't agree with reality.
I need to go back & read his statements again.
