Yes or no.

 From the articulation by Pat for my viewpoint here,,
my understanding of Conneg is different from what the Conneg that was 

But whether I am confused or not depends on the precise definitions of 
resource, representation and precise specification of their 
relationships.  I can say that I am confused w.r.t. the lack of a 
precise definition of current specifications.  Or I can say, I am not 
confused w.r.t. my understanding of Conneg.  Is that fair?
