By specification.  If you have

<foo:bar ID="A">
  <spam rdf:resource="monty"/>
  <eggs>python</eggs>
</foo:bar>

Then the RDF syntax specifies that foo:bar is a typed node, and this 
represents a resource, #A with rdf:type foo:bar, a spam property with 
resource-type property monty, and an eggs property with literal type value 
python.
