A concept or dimension relationship node resolves into a tree of structural nodes, defined by networks of concepts or explicit dimension members in the DTS. Therefore the component in the definition tree corresponds with a block of cells in the layout.
The screenshot at left shows a table definition containing a concept relationship node. The screenshot at right shows the corresponding network of concepts, in this case defined in the presentation linkbase.
A relationship node has exactly one aspect constraint: concept or explicit dimension. Therefore the header of each layout cell is the concept's label (if it exists) or its qualified name. The Details tab of the Details entry helper shows the properties of the relationship node, whereas the Constraints tab provides the aspect constraint (set) that is defined by the cell focused in the layout.
