The Initial Example in [1], as shown in Figure 2, shows Profile X as a profile of "Dublin Core Terms" (*), identified in the example as [2]. The specification at [2] has evolved, and continues to evolve, over a long timeframe. This is not unusual - think FOAF, Schema.org, even SKOS and RDF. For RDF namespaces, best practice turned out to be _not_ to include versioning information in URIs. DCMI stopped doing it after http://purl.org/dc/elements/1.1/ (the next one to be coined was http://purl.org/dc/terms/). FOAF still uses http://xmlns.com/foaf/0.1/, but changing the URI at this point would be quite disruptive with no obvious gains (other than aesthetic).
