Hi Alapan,

one comment to our discussion:

Maybe there is still a misunderstanding, what the action element is.
It simply "names" the action that always comes with a permission or duty or
prohibition.

For example a duty to pay some amount would look like that:

o-ex20:duty id="d01" relaxed="true">  
          <o-ex20:payment>
             <o-ex20:amount currency="EUR">0,50</o-ex20:amount>
          </o-ex20:payment>
          <o-ex20:hasConstraint id="c02"/>
</o-ex20:duty>

where "payment" is the action element. There is no duty without an action or
"if there's no action defined then there is not duty".

And after all: when expressing a prohibtion the duty element is optional
(and implicitly the action element too).
Does that make sense to you or is still something unclear?

<sg> I need some more information on this issue because I don't understand
 the conflict that you have. Is it because the Duty always refers to an
 Action?

<aa> Yes - a duty requires an action. However, you might want a prohibition
 license that allows everything - hence there will be no action to link
 with the duty.
