Re: [poe] Clarify contradictory values of conflict attribute

I added a new example that recalls some of the elements Simon 
highlighted above. I didn't provide any solution in the example, as I 
believe we need first to agree on it. 

To me, in case of direct dependency, and 
conflict=perm/conflict=prohibits for the two policies, the merging 
results into an invalid policy. 

In case of explicit dependency and conflict=perm/conflict=prohibits, 
then they can coexist, having in the merging policy the permission use
 and the prohibition display. But what about the conflict values here?

The case of implicit dependencies needs to be dealt with by including 
in the vocabulary the fact the e.g., sharing implies distributing. 
Again, what about the the conflict values?

Establishing a fix default value in case of merging of policies with 
conflicting conflict values is difficult. In general, prohibitions 
should have the priority over permissions.
