several broken rules in RL?

Hi!

Last Minute Bug Report (technical).

In OWL 2 RL, the rule for owl:AllDisjointClasses seems wrong to me:

  <http://www.w3.org/2007/OWL/wiki/Fragments_Proposal#cax-adc>

  Premise:

    T(?y, rdf:type, owl:AllDisjointClasses)
    LIST[?y, ?c1, ..., ?cn]
    T(?x, rdf:type, ?ci)
    T(?x, rdf:type, ?cj)

Here, the list of classes seems to be put directly to the "root node" "?y". But it should be the RHS of "owl:members", although there is no mentioning of "owl:members" (why?).

This is not the only case. Analog for:

  * owl:AllDifferent <http://www.w3.org/2007/OWL/wiki/Fragments_Proposal#eq-diff2>
  * owl:propertyChainAxiom <http://www.w3.org/2007/OWL/wiki/Fragments_Proposal#prp-spo2>
  * owl:AllDisjointProperties <http://www.w3.org/2007/OWL/wiki/Fragments_Proposal#prp-adp> 

Note: owl:AllDifferent uses both "owl:members" and "owl:distinctMembers".

Michael
