The EBNF here is condensed for human readability; in particular, the italicized "rdf" is used to represent a variable namespace name rather than the more precise BNF notation "'<' NSname ':...'" and the requirement that the property and type names in end-tags exactly match the names in the corresponding start-tags is implied by the XML rules. [...] RDF serialization syntax takes the form: [1] RDF ::= '<rdf:RDF>' expression* '</rdf:RDF>' [end of excerpt] ('rdf' in the above is italicised in the original HTML.) At first glance this looks as if 'rdf' is hardcoded as the namespace prefix, but I think this is just an artifact of the convenience shorthand being adopted. The phrase "'rdf' is used to represent a variable namespace name" makes it pretty clear that other prefixes could be used instead. Dan xml-dev: A list for W3C XML Developers.
