ill-formed lists in OWL Full

I can't see any constraint in the editors draft of OWL Full semantics that 
forces rdf:first to be functional or rdf:rest to be functional even on the 
class of OWL Lists. OWL Lists are identified with I(rdf:LIst) which does not 
be default denote well-formed lists, but any structures at all really. 
Although optionally we can constrain the vocabulary in the obvious ways, I 
don't see this constraint being taken up.

I imagine that this is a bug.
