/**
 * A ConfigurationItem consist of the configuration section to ask for and an additional scope URI.
 * The configuration section asked for is defined by the server and doesn’t necessarily need to
 * correspond to the configuration store used by the client. So a server might ask for a configuration
 * {@code cpp.formatterOptions} but the client stores the configuration in an XML store layout differently.
 * It is up to the client to do the necessary conversion. If a scope URI is provided the client
 * should return the setting scoped to the provided resource. If the client for example uses
 * EditorConfig to manage its settings the configuration should be returned for the passed resource
 * URI. If the client can't provide a configuration setting for a given scope then null needs to be
 * present in the returned array.
 * <p>
 * Since 3.6.0
