No no. You can serialize an rdf graph into any number of different  
xml/rdf documents. When you crystalize it, you force a particular  
structure on the rdf serialization. So for example in the RSS 1.1  
case you force the document to start with the <Channel> element,  
specify that it can contain <title>, <lint>, <items>..., and specify  
that <items> contain <item>s which contains <title>,<link>, ...  
elements. You do this using a Relax-NG schema.

see the RSS1.1 spec for a good example of this:
