That's not an equivalence, it's just an example of how you might generate a reverse-DNS style name if you choose to use them. For purposes of RDF conversion, "com.example.foo" is equivalent to "http://www.w3.org/1999/xhtml/microdata#com.example.foo ". Otherwise, you can treat the space or reverse-dns names as completely separate from URIs. - Maciej
