      public class DefaultScopeDescription
      extends ISOMetadata
      implements ScopeDescription

  Description of the class of information covered by the information. The following properties are mandatory or conditional (i.e. mandatory under some circumstances) in a well-formed metadata according ISO 19115:
  `MD_ScopeDescription` `├─attributeInstances……` Attribute instances to which the information applies. `├─attributes…………………………` Attributes to which the information applies. `├─dataset…………………………………` Dataset to which the information applies. `├─featureInstances…………` Feature instances to which the information applies. `├─features………………………………` Features to which the information applies. `└─other………………………………………` Class of information that does not fall into the other categories to which the information applies.
  ISO 19115 defines `ScopeDescription` as an union (in the C/C++ sense): only one of the properties in this class can be set to a non-empty value. Setting any property to a non-empty value discard all the other ones.
  Limitations
  - Instances of this class are not synchronized for multi-threading. Synchronization, if needed, is caller's responsibility.
  - Serialized objects of this class are not guaranteed to be compatible with future Apache SIS releases. Serialization support is appropriate for short term storage or RMI between applications running the same version of Apache SIS. For long term storage, use `XML` instead.

    - #### DefaultScopeDescription

          public DefaultScopeDescription()

      Creates an initially empty scope description.

    - #### DefaultScopeDescription

          public DefaultScopeDescription(ScopeDescription object)

      Constructs a new instance initialized with the values from the specified metadata object. This is a shallow copy constructor, since the other metadata contained in the given object are not recursively copied.

      If the given object contains more than one value, then the first non-null element in the following list has precedence (from wider scope to smaller scope): dataset, features, attributes, feature instances, attribute instances and other.

      Parameters:
        `object` - the metadata to copy values from, or `null` if none.
      See Also:
        `castOrCopy(ScopeDescription)`

  - ### Method Detail

    - #### castOrCopy

          public static DefaultScopeDescription castOrCopy(ScopeDescription object)

      Returns a SIS metadata implementation with the values of the given arbitrary implementation. This method performs the first applicable action in the following choices:
      - If the given object is `null`, then this method returns `null`.
      - Otherwise if the given object is already an instance of `DefaultScopeDescription`, then it is returned unchanged.
      - Otherwise a new `DefaultScopeDescription` instance is created using the copy constructor and returned. Note that this is a shallow copy operation, since the other metadata contained in the given object are not recursively copied.
      Parameters:
        `object` - the object to get as a SIS implementation, or `null` if none.
      Returns:
        a SIS implementation containing the values of the given object (may be the given object itself), or `null` if the argument was null.

    - #### getDataset

          public String getDataset()

      Returns the dataset to which the information applies.
      Example: If a geographic data provider is generating vector mapping for thee administrative areas and if the data were processed in the same way, then the provider could record the bulk of initial data at `ScopeCode​.DATASET` level with a “Administrative area A, B & C” description.
      Specified by:
        `getDataset` in interface `ScopeDescription`
      Returns:
