You can create some pretty awesome messes even without OWL:
# An rdf:List that loops around...
<#mylist> a rdf:List ;
rdf:first <#Alice> ;
rdf:next <#mylist> .
# A looping, branching mess...
<#anotherlist> a rdf:List ;
rdf:first <#anotherlist> ;
rdf:next <#anotherlist> .
They might be messy, but they are *possible* structures using
pointers, which is what the RDF vocabulary describes. Its just about
impossible to guarantee that messes can't happen when all you are
doing is describing structures in an open-world setting. But I think
the cure is to stop thinking that possible-messes are a problem to be
solved. So, there is dung in the road. Walk round it.
