RDF defines several container elements. The rdf:Seq element groups together resources order of which is significant. The
individual resources are either individually numbered with rdf:_1, rdf:_2, rdf:_3 ... , or generalized form rdf:li can be

in the best possible state, it preffers to lend the first specified book (M124) as often as possible. Compare with
Example 12 in which the order was insignificant ant rdf:Alt was used
