I'm sorry, but I don't think that is right.  You cannot use the 
rdf:parseType syntax to create the list, but you can spell out the 
structure explicitly, e.g.:

<rdf:Description>
   <foo:listValuedProp>
     <rdf:List rdf:nodeID="head"/>
   </foo:listValuedProp>
</rdf:Description>

<rdf:List rdf:nodeID="head">
   <rdf:first>first</rdf:first>
   <rdf:rest>
     <rdf:List rdf:nodeID="l2"/>
   </rdf:rest>
</rdf:List>

<rdf:List rdf:nodeID="l2">
   <rdf:first>second</rdf:first>
   <rdf:rest>
     <rdf:List rdf:nodeID="l3"/>
   </rdf:rest>
</rdf:List>

<rdf:List rdf:nodeID="l3">
   <rdf:first>first</rdf:first>
   <rdf:rest>
     <rdf:nil/>
   </rdf:rest>
</rdf:List>
