In Examples 60, 61, and 62 , both accessURL and downloadURL are included, and they are the same URLS. These are all downloadURLs, so I don't think accessURL should be included in the example rdf.
example from 61:
dcat:accessURL <https://mvcr1.opendata.cz/czechpoint/data.tar> ;
dcat:downloadURL <https://mvcr1.opendata.cz/czechpoint/data.tar> ;
