using duty in odrl:Set (without sorrounding permission)

Hi!

Using ODRL to represent license declarations, (sometimes) requires the 
use of duties without "attaching" them to respective permissions (cf. 
[1]).

For example, the policy defined underneath represents a CC-BY-NC 
license:

:licCC-BY-NC a odrl:Set;
    odrl:permission [
        a odrl:Permission;
        odrl:action odrl:reprodice;
        odrl:action odrl:distribute;
        odrl:action odrl:derive
    ] ;
    odrl:prohibition [
        a odrl:Prohibition;
        odrl:action odrl:commercialize
    ] ;
    odrl:duty [
        a odrl:Duty;
        odrl:action odrl:attribute;
        odrl:action odrl:attachPolicy
    ] .

But that would in general contradict the ODRL core model as stated in 
[2] if I'm not mistaken? (Assuming the representation of the 
relationship between Asset & Policy uses the wrong arc)

So what's the general consensus about that?

cheers,
