/**
 * Abstract subclass of BaseRequestParser, which allows retrieving
 * configured maxRecords, and earliest and latest timestamp config from an
 * delegate instance.
 * 
 * This class is intended to be overridden and used in conjunction with a
 * CompositeRequestParser: The CompositeRequestParser(or subclass thereof) will
 * hold actual configuration data, and all composed RequestParsers will inherit
 * from this, accessing the configured data on the wrapped instance.
 *
 * For examples, please see {Path,Form,OpenSearch,Composite}RequestParser in
 * this package.
