/**
* Describes transaction attributes on a method or class.
*
* This annotation type is generally directly comparable to Spring's
* {@link org.springframework.transaction.interceptor.RuleBasedTransactionAttribute}
* class, and in fact {@link AnnotationTransactionAttributeSource} will directly
* convert the data to the latter class, so that Spring's transaction support code
* does not have to know about annotations. If no rules are relevant to the exception,
* it will be treated like
* {@link org.springframework.transaction.interceptor.DefaultTransactionAttribute}
* (rolling back on runtime exceptions).
