The issue was closed with a resolution to keep as it was. I think I said 
I could live wit it, but now I'm not completely sure.

But it also says " The same Link header may be provided on other 
responses". In Marmotta we decided to include it for all responses. And 
there the conflict appears. Maybe we should reconsider that.

Well, besides the practical issue of not been able to get the associated 
LDP-RS, there is the issue about using describedby with two different 
semantics.

Let's talk about it in the call.
