As I mentioned briefly last week...
http://www.w3.org/2003/07/03-webont-irc#T17-26-38

RDF Core has decided to change the semantics of rdfs:subClassOf
and subPropertyOf...

[[
10: Issue horst-01

DECISION: to close horst-01 by moving to intensional semantics for
subClassOf ('if' rather than 'if and only if'), and by including new
rules rdfs12a and rdfs12b in additional part of rules section.
[...]

ACTION: DanC to inform WebOnt. context,
http://www.w3.org/2003/06/27-rdfcore-irc#T15-21-11

ACTION: PatH to respond to the commentor (ter horst). context,
http://www.w3.org/2003/06/27-rdfcore-irc#T15-21-48
]]

I think the only impact is on S&AS, and Peter said
he was well prepared for it; he'd only have to
un-comment some stuff from his source.
