RE: Does RDF overlap w/XML Schema

Perhaps this excersize would clarify the differences between RDF and XML
Schema definition languages:

1) Write an XML Schema definition or DTD for RSS
2) Write an RDF Schema definition for RSS

(hint: to do correctly (2) is easy as it doesn't try to constrain
syntactical issues such as element order)
