Yes - in fact I am moving from long established (working) simple perl 
code and local files which present container members as <RDF:li>.  I 
have also followed an example at xulplanet (see 
http://www.xulplanet.com/tutorials/mozsdk/rdfsyntax.php) written to 
demonstrate mozilla/rdf and the rdf:_n syntax gives empty containers 
whereas the rdf:li syntax works as expected.

I suspect what I will need to do is to create a new serialization class 
extending RdfSerializer and override the writeContentStatements function 
(I know its meant to be private but its better than hacking the core 
code!) to rewrite the RDF:_n tags as RDF:_li and adding a custom 
attribute to pass the order number to firefox.  I can then use this 
custom attribute to create the appropriate RDF:_n based modification 
statements I send back from the browser to the server. 

It should work but is a bit of a pain :-(.
