Ignoring the wanrings which are just warning (no base in force so
relative URIs not resolved: use "-b" to set the base)
this is RDF/XML striped syntax:
<foaf:Person rdf:ID="me"> class (and bnode id)
<PubKey rdf:nodeID="KeyA"> so this is a property
<foaf:name>key A</foaf:name> has to be a class ... but isn't
</PubKey>
</foaf:Person>
I don't think you can have both rdf:nodeID on a property and also have
content. But as the content suggests a property, there is striping
misalignment.
