```
public static final Symbol sysDatasetDescription
```
    Context key for the dataset description (if any). See the SPARQL protocol.
    A dataset description specified outside the query should override a dataset description in query and also the implicit dataset of a service. The order is:
    1. Dataset description from the protocol
    2. Dataset description from the query (FROM/FROM NAMED)
    3. Dataset of the service
    Use in other situations should reflect this design. The value of this key in a Context must be an object of type DatasetDescription.
