Determines the attributes to retrieve during
SearchApiOp and
Org.IdentityConnectors.Framework.Api.Operations.SyncApiOp.
This option overrides the default behavior, which is for the connector to return exactly the set of attributes that are identified as AttributeInfo#isReturnedByDefault() returned by default in the schema for that connector.
This option allows a client application to request additional attributes that would not otherwise not be returned (generally because such attributes are more expensive for a connector to fetch and to format) and/or to request only a subset of the attributes that would normally be returned.
