I think that I haven't thought hard enough and that Pat
has some good arguments in
http://lists.w3.org/Archives/Public/www-webont-wg/2002Sep/0331.html
so I withdraw rule10 and rule11

I've tested those 2 testcases and had a proof found
after adding following 2 closure rules
--------------------------------------------------------
| IF | THEN
--------------------------------------------------------
:rule11 | ?A rdfs:subClassOf ?B . |
| ?p rdfs:domain ?A . | ?p rdfs:domain ?B .
--------------------------------------------------------
:rule12 | ?A rdfs:subClassOf ?B . |
| ?p rdfs:range ?A . | ?p rdfs:range ?B .
--------------------------------------------------------

Domain & range test case, in n3, will RDF/XML latter.
1:[[
eg:prop rdfs:range eg:A .
eg:A rdfs:subClassOf eg:B .
rdfs-entails
eg:prop rdfs:range eg:B .
]]
(i.e. in english,
every object of a eg:prop is an eg:A.
every eg:A is an eg:B,
thus
every object of an eg:prop is an eg:B).
Similarly
2: [[
eg:prop rdfs:domain eg:A .
eg:A rdfs:subClassOf eg:B .
rdfs-entails
eg:prop rdfs:domain eg:B .
]]
As Jan says, maybe we have misspelt rdfs:subSetOf.
If we don't have this, Peter has to work harder anyway; and doing it four
times over is about the same as doing it once. So if Pat is changing his
mind on these ones, I would tend to want to leave the subClassOf ones alone
too.
