...and I'm puzzled. Maybe I took 'no way to say' in a stronger sense
than intended; additional vocabulary (not currently provided by RDF
Core) would let you do just this, unless I'm missing something...
<rdf:Bag>
<rdf:_1>1</rdf:_1>
<rdf:_2>2</rdf:_2>
<util:bagsize>7</util:bagsize> <!-- or whatever, eg util:last... -->
</rdf:Bag>
