Custom container with ordered elements of a particular class

Question

I would like to declare in my schema a container class that contains ordered elements of a particular class. I figured that the simplest way to declare that the elements must be ordered was to declare the container a rdfs:subClassOf rdf:seq.

:MyContainer rdfs:subClassOf rdf:seq.
:MyElement rdf:type rdfs:Class.
:elementProperty1
  rdf:type rdfs:Property;
  rdfs:domain :MyElement.

In addition to the above I would also like to convey the following information in the schema:

• The statements :ContainerInstance rdf:_1 Object and :ContainerInstance rdf:type :MyContainer entail that Object rdf:type :MyElement.

• The statements Subject rdf:_1 :ElementInstance and :ElementInstance rdf:type :MyElement entail that Subject rdf:type :MyContainer.

Of course, any instance of rdfs:ContainerMembershipProperty (rdf:_1, rdf:_2, rdf:_3 …) could appear in place of rdf:_1 above.
