One conclusion we might draw from this idea: we should target
organizations that don't have XML expertise.  XML and RDF are different,
of course, but they are *close enough* that it's hard to justify
learning both.  In other words, make the point that you don't need to
know ANYTHING ABOUT XML in order to use Semantic Web technogies.

So maybe that's:

     Myth: RDF is based on XML

     Fact: No, RDF can use XML when it makes sense to do so, but RDF
           works very well without XML, and people can use Semantic Web
           technologies quite effectively without knowing anything about
           XML.

(This obvious relates to Kingsley's issue with the traditional layer
cake, which shows RDF based on XML.)

Of course, let's not forget the flip side:

     Myth: RDF and XML are competing technologies

     Fact: Although users sometimes do have to make a choice between
           them, RDF and XML generally solve very different problems.
           Do spreadsheet programs and word processing programs compete?
           Yes, a user has to chose one or the other for a given task,
           but in general one is much better suited than the other, so
           there is little real competition.
