Because it felt verbose and ugly writing

c1 rdfs:subClassOf c2 .
c2 rdfs:subClassOf c1 .

I leave it to the read to imagine the prettiest possible serialization 
of this in RDF/XML. RDFa might fare slightly better...

ps. I get the impression folk may have been using equivalentClass with 
properties (like rdfs:label); that shouldn't work at all.
