Mike - I am trying to workout if there is any "machine code" differences
as this is something we may like to capture in the ODRL/CC Profile [1].

There are obvious semantic differences between the licenses, but If
we look at these two:

<License 
rdf:about="http://creativecommons.org/licenses/nc-sampling+/1.0/";>
   <permits rdf:resource="http://web.resource.org/cc/Reproduction"; />
   <permits rdf:resource="http://web.resource.org/cc/Distribution"; />
   <permits rdf:resource="http://web.resource.org/cc/DerivativeWorks"; />
   <requires rdf:resource="http://web.resource.org/cc/Notice"; />
   <requires rdf:resource="http://web.resource.org/cc/Attribution"; />
   <prohibits rdf:resource="http://web.resource.org/cc/CommercialUse"; />
</License>

<License rdf:about="http://creativecommons.org/licenses/by-nc/2.0/";>
   <permits rdf:resource="http://web.resource.org/cc/Reproduction"; />
   <permits rdf:resource="http://web.resource.org/cc/Distribution"; />
   <permits rdf:resource="http://web.resource.org/cc/DerivativeWorks"; />
   <requires rdf:resource="http://web.resource.org/cc/Notice"; />
   <requires rdf:resource="http://web.resource.org/cc/Attribution"; />
   <prohibits rdf:resource="http://web.resource.org/cc/CommercialUse"; />
</License>

They have the same properties, but are different licenses.

I know that RDF-folk will argue that these are different resources,
hence are different things (licenses).

In the non-RDF world (with good ol' XML Schema:-), to represent the 
above,
we need to add some differentiation. We could take the 
"nc-sampling+/1.0/"
URI and turn it into an element, but that URI represents the "whole"
license.
