But I am struggling with defining an edge (named DocLink in the semantic model) that connects the documentation node with any existing model element. More precisely, I do not know how to configure the target mapping of the edge since I cannot select a specific mapping; the target should be any node of the diagram.

No way to do that. Currently, you must select all node mappings in the
"Target Mapping" list of your edge mapping DocLink.
