1. CARA has implemented "aboutEach". 

2. I don't think rdf:aboutEach requires processing of sub-property relations: 

   Members of containers must have rdf:_nnn arcs by RDF M&S - 
   without any inferences required to deduce something like that (see RDF M&S End of sec5). 
   

3. Competing use of explicit numbering (rdf:_1 ...) and rdf:li - as "Refactoring" 
   seems to allow - is awkward, confusing and yields erronous results:

   <rdf:Bag rdf:_1="one">
   <rdf:li>one</rdf:li>
   </rdf:Bag> 

   ARP constructs from it 3 triples: Get [genID --rdf:_1--> one] twice. Statements in a model form a set, 
   which has triples as elements.  


   The construction currently is not equivalent with
   <rdf:Bag>
   <rdf:li>one</rdf:li>
   <rdf:li>one</rdf:li>
   </rdf:Bag> 

   which get's correctly processed as [genID --rdf:_1--> one, genID --rdf:_2--> one]. 

   Explicit numbering is of fairly limited use. Is there any format specified for explicit numbering? 
   ARP excepts rdf:_-1 without any complaint.  
   


4. Which thoughts the wg has about xml:lang ? 
   It should either be removed from RDF or should create triples - 
   


Cheers
