In general, the ability, or lack thereof, to express a given constraint 
in any schema language has been regarded as an unimportant consideration 
for Web Forms content models (and hence, by inference, is unimportant 
for Web Apps content models) . Therefore this isn't a good argument 
against using <li> in this way. On the other hand, if legacy UAs have 
some problem with <li> outside a HTML 4 list container, that would be a 
good argument against this (IMHO rather attractive) proposal. I'd be 
surprised if that were the case though since such a restriction would 
probably break real sites.
