	The term 'typedNode' is part of the formal grammar for RDF [production
6.13]. What this says is that

<rdf:RDF xmlns:oh="http://www.openhealth.org/types#"
<oh:person
	rdf:about="http://www.openhealth.org/people/1234">

	<oh:person.fullname>Jonathan A. Borden</oh:person.fullname>
	<oh:email>jonathan@openhealth.org</oh:email>

</oh:person>
</rdf:RDF>

is precisely equivalent to:

<rdf:RDF xmlns:oh="http://www.openhealth.org/types#"
<rdf:Description xmlns:oh="http://www.openhealth.org/types#"
	rdf:about="http://www.openhealth.org/people/1234">

	<rdf:type rdf:resource="http://www.openhealth.org/types#person">
	<oh:person.fullname>Jonathan A. Borden</oh:person.fullname>
	<oh:email>jonathan@openhealth.org</oh:email>
</rdf:Description>
</rdf:RDF>
