+ * General notes about configuration classes.
+ *
+ * Each Yaml node that exists in the yaml schema,
+ * as defined by https://github.com/open-telemetry/opentelemetry-configuration
+ * is represented by a C++ class.
+ * Special comments are used to relate the C++ class to
+ * the Yaml node it represents.
+ *
+ * YAML-SCHEMA: points to the relevant file within the
+ * opentelemetry-configuration repository
+ * YAML-NODE: points to the relevant node within the file.
+ *
+ * For example,
+ *   C++ class opentelemetry::sdk::configuration::Configuration
+ * corresponds to
+ *   Yaml node OpenTelemetryConfiguration,
+ * in file
+ * https://github.com/open-telemetry/opentelemetry-configuration/blob/main/schema/opentelemetry_configuration.json
