RDF/XML syntax for property chain example error?

In the property chain example in section
http://www.w3.org/2007/OWL/wiki/Primer#More_Expressive_Modeling
the Manchester syntax is:

SubProperty: hasSpouse o hasSon hasSon
SubProperty: hasSpouse o hasDaughter hasDaughter

But I think the RDF/XML syntax shown below is incomplete.  It only shows the List of the two 
properties, but does not include the owl:propertyChain as required by
http://www.w3.org/2007/OWL/wiki/Mapping_to_RDF_Graphs#Translation_of_Axioms_without_Annotations
