Can I ask a really stupid question:  Why can't this just be:

[AnyResource]--properName-->"(name string)"

What is the utility of the extra node?  Can't the schema for "properName" indicate that
its object is expected to be a public string just like "rdf:value"?  Also can't
{[AnyResource]--rdf:Type-->[ProperlyNamed]} be inferred by relationships hung off of
properName ?
