The reverse mapping would have to be such that the rdf:list  
vocabulary was mapped to the new vocabulary for OWL 1 ontologies.
The question would be whether there were any ontologies that could  
ambiguously be valid OWL 2 ontologies that used the rdf:list  
vocabulary in axioms and at the same time be owl 1 ontologies that  
used the list vocabulary as syntax.
