I read carefully the new RDF M&S WD

I found some errors in the examples.

1- In 7.2 Aggregates, the rdf:Bag is closed with a rdf:bag (thanks
to http://www.w3.org/RDF/Implementations/SiRPAC/)

2- More important, the second and third examples in section 7.4 Dublin Core
Metadata seems to be wrong.

The third defined property in the second example is :
   <dc:Contributor dcq:AgentType="dcq:Editor">Amy Friedlander</dc:Contributor>

This writing corresponds to the second simplifcation form in section 2.2.2
and to production 6.10 and 6.11 in section 6.
But, this form can be used 
"for specific property statements when the property value is another 
resource and the values of any properties given in-line for this
second resource are strings"

In our case, this is not true : the property value is the string 
"Amy Friedlander" !
This is the same for property "dc:Relation" in second and third example.
For imformation, SiRPAC generates some strange output with these RDF input
 but does not complain.

The initial aim of the property "dc:Contributor" seems to say :
"Ressource 'http://www.dlib.org/dlib/may98/05contents.html' has 'dc:Contributor'
'Amy Friedlander', and this  contribution has for 'dcq:AgentType' 'dcq:Editor'"

If I'm right, this should be written :
   <dc:Contributor ID="contrib">Amy Friedlander</dc:Contributor>
<rdf:Description about="#contrib">

I put on the web some drawing of reified examples from the WD 

Hope this helps.
