I agree that step 10 is not relevant to this discussion.  I was 
conflating two issues.  Sorry!

I believe this is what Mark intended, and it enables the (edge) case 
that you can stop chaining by inserting an empty rel, which was 
something we had discussed at one time.

I think it is certainly editorial.  I am not certain that it makes Ben 
or Mark happy though.  I personally don't care what the answer is.  I 
would also be happy with changing text in section 5.4.3 by adding to the 
end of the conditions "Regardless of the datatype of the attribute, if 
evaluation of the attribute value for CURIEs and URIs results in no 
valid URIs, a conforming processor MUST behave as if the element has no 
specification of the attribute (e.g., as if there is no entry for the 
attribute in the DOM tree at all)."
