There is no DTD for the RDF syntax because RDF data is likely to be
embedded in a variety of different document types. Also the RDF
syntax uses a variety of element and attribute names to represent
intermingled  classes, properties and resource drawing on multiple
independently defined vocabularies. This is pretty much impossible to
anticipate in a single monolithic "RDF DTD".
