The english text is meant to hark to the example, not
to be a formal specification of the relationships.

The formal spec doesn't constrain the number of
representations, so it allows zero or more.

A relevant excerpt from idRes.rdf:

<owl:ObjectProperty rdf:about="webarch#representation"> 
  <rdfs:label>representation</rdfs:label>
  <rdfs:domain rdf:resource="webarch#Resource"/>
  <rdfs:range rdf:resource="webarch#Representation"/> 
</owl:ObjectProperty>
