Comment on Formal Semantics: typed node

Comment on http://www.w3.org/TR/2008/WD-powder-formal-20080709/, Formal 
Semantics

The text says, right before 3-13:

[[[
Following on from the previous example, it is also permissible to have 
an RDF Class embedded in the descriptor set as long as there are no 
blank nodes. Typed nodes are allowed, as shown in Example 3-13.
]]]

This sentence is misleading. The construction:

<owl:hasValue>
   <ex:Red>
     <ex:hex>ff0000</ex:hex>
   </ex:Red>
</owl:hasValue>

_does_ define a blank node that happens to be an instance of type 
ex:Red. On the other hand, 'typed node' is not an RDF notion but an 
RDF/XML notion, ie, it would be better to stick to general RDF/OWL 
terms. I guess this needs some re-write...

Cheers
