Draft Protocol question -- Creating a child basic container for annotations

The LDP 1.0 Primer (http://www.w3.org/TR/ldp-primer/, Editor’s draft dated today) gives an example of how to create a new basic container inside an existing basic container (modified from example 6 in section 2.3):

 

In Turtle and assuming the parent container is http://example.org/containerA/

 

POST containerA/ HTTP/1.1

Host: example.org

Content-Type: text/turtle

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

Slug: timsAnnos

 

@prefix ldp: <http://www.w3.org/ns/ldp#> .

@prefix dcterms: <http://purl.org/dc/terms/> .

<> a ldp:Container, ldp:BasicContainer;

   dcterms:title "Tim’s Annotations" ; 

   dcterms:description "This container will contain Annotations created by Tim." .  

 

This should result in a new child basic container, http://example.org/containerA/timsAnnos/

 

The key, according to the text accompanying the original example in the Primer is the inclusion of the Link: <http://www.w3.org/ns/ldp/BasicContainer>; rel="type" header.  Following this logic, if I want to make sure that the new container is understood by the LDP Server to be a container for annotations, should I also include an additional link in the Post request Link header? i.e.:

 

POST containerA/ HTTP/1.1

Host: example.org

Content-Type: text/turtle

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

          <http://www.w3.org/TR/annotation-protocol/constraints>; rel="http://www.w3.org/ns/ldp#constrainedBy"

Slug: timsAnnos

 

@prefix ldp: <http://www.w3.org/ns/ldp#> .

@prefix dcterms: <http://purl.org/dc/terms/> .

<> a ldp:Container, ldp:BasicContainer;

   dcterms:title "Tim’s Annotations" ; 

   dcterms:description "This container will contain Annotations created by Tim." .  

 

Apologies if this is dealt with somewhere in the Protocol draft and I missed it.

 

Thanks,
