Ok, everytime I think I have a useful idea it is already there and better implemented :) It is nice that I can do it either one or the other way. But the link text is always the title of the target structure. I need the link label to be displayed. In the second approach can do it manually with *Label>/some...* (does not work with the first approach *Label>value:...*. Is there a way to display the link label? 

thanks,

norbert

This seems only possible if you have a pier context and renderer at the same time which is not really the case as long as you are staying inside PRValueLink.
