Pat,
What about generalizing rdfs12 to
{: rdfs:fyi :rdfs12a. ?Q rdfs:domain ?Y. ?P rdfs:domain ?X.
?P rdfs:subPropertyOf ?Q} => {?X rdfs:subClassOf ?Y}.
{: rdfs:fyi :rdfs12b. ?Q rdfs:range ?Y. ?P rdfs:range ?X.
?P rdfs:subPropertyOf ?Q} => {?X rdfs:subClassOf ?Y}.
Then the cases that Peter brought up are following
(I've tested that and the other RDFS and OWL are
in status quo, be it with some more steps).

rdfs:subClassOf rdfs:subPropertyOf xxx .
xxx rdfs:domain yyy .
RDFS-entails
rdfs:Class rdfs:subClassOf yyy .
but this does not come out of the RDFS closure rules.
