+## Known Issues
+
+- **JSON-LD/RDFXML format pull** (`DEMO.md:160,163,449-453`): The layer1-service does not properly honor the Accept header for different RDF formats. Pulling with `--format jsonld` or `--format rdfxml` will fail because the server always returns Turtle format.
+- **Merge/diff operations** (`DEMO.md:248,390-394`): The merge command with `--no-commit` and subsequent diff creation fails with "Not implemented (formulae, graph literals)" due to a TriG parsing issue in the layer1-service.
