/**
 * Informs the {@code RxMicro Annotation Processor}, that a header model field with array type
 * must be converted to the repeating HTTP header.
 *
 * 
 * By default, the RxMicro framework converts header model value as string, separated by the
 * {@value io.rxmicro.http.HttpValues#STRING_ARRAY_DELIMITER}) symbol. For example:
 *
 * 

 * {@code HeaderName: value1|value2|value3.}
 *
 * 

 * If this annotation is present, result will be:
 *
 * 

 * {@code HeaderName: value1}
 * {@code HeaderName: value2}
 * {@code HeaderName: value3}
 *
 * 
 * Supported for REST client HTTP request and REST controller handler HTTP response models only!
