So at least we have agreement on the semantics of the "type" Relation 
i.e., it denotes the same concept as 
<http://www.w3.org/1999/02/22-rdf-syntax-ns#type>. Thus, you have:

Link: <http://www.w3.org/ns/ldp#Container>; rel="type"

having the same meaning as the 3-tuple:

  { <> a ldp:Container }

Which goes to demonstrate that RDF's abstract syntax has nothing to do 
with Media Types. This simple example shows that RDF model theory 
semantics (which are abstract in nature) can be applied at the following 
levels:

1. HTTP
2. RDF documents
3. Even HTML documents -- by using <link/> reflect the very same 
Relation semantics expressed via the Link: header.
