• The W3C RDF Core Working Group published a new document in December of 2001 updating RDF syntax (RDF/XML Syntax Specification (Revised)). The new working draft recommends that all attributes belonging to the RDF namespace be clarified with the prefix associated with the RDF namespace (with the rdf prefix in CellML). Thus, all about attributes mentioned should have the rdf prefix.
