You do not need to create a specific concept/class in your DSL.
Relation based Edge i sthe well choice in your case because your want to
represent a relation between two elements (represented by the "type"
feature). The Domain based Edge could be used if you had the DataTypeRef
(like Association in UML) in your DSL. But see my next comment.
Or am I missing something in the .odesign file [2] ?
Yes you are missing something: you choose the "list" children
presentation for your container and Sirius is not currently able to draw
edges from/to list elements (edges from/to the parent List container is
a supported structure).
You could use some bordered node (right click your sub node mapping,
refactor > Move to Contained/Bordered Node) or create a new Bordered
node on your container mapping. Then if you link your edge mapping to
this border mapping, your edges will be computed and displayed.

First remark: all the fields whose name is diplayed in a bold font and
ended by a '*' are required. So you must put an id for all the mapping
and tools you defined in your odesign.
Then I looked into your odesign, and I think that your edge problem will
be solved by the add of an id, because now your two edge mappings have
the same empty id (if your try to validate your odesign, several errors
should tell you this).

The attributes are now created as bordered nodes and displayed on the
border of the Class lists. Sirius places them to avoid overlap, and
starts from the upper left corner. You might try to write and execute a
command to change their layout (the layout constraint of the GMF
Notation Nodes corresponding to each bordered Attribute node) and call
it after/during your creation command.
