I thought that issue had been resolved earlier in:


I had assumed the interpretation was that if resource R has to properties
sp1 with value v1 and sp2  with value v2, where sp1 and sp2 are both
subproperties of p, then has R has two properties P, one with value v1 and
the other with value v2.


  sp1(R, v1) & sp2(R, v2) & subPropertyOf(sp1, p) & subPropertyOf(sp2, p) =>

  p(R, v1) & p(R, v2)

I couldn't find any references to this problem at the uri you gave.  Which
section is it in.
