[hibernate-dev] Hibernate Envers question

Hello! I wondered how envers works/could work in a JPA portable way. Are you using somehow a entity listener approach or so? Does the the code needed for envers really depend on the hibernate core stuff or does hibernate just offer a more relaxed contract in respect to entity listeners? I was just wondering why nobody proposed the auditing stuff to be included in the jpa spec since there were already many requests for auditing for other jpa impls. IMO it's a fairly common issue to address auditing and therefore worth to, not necessarily be standardized but, at least be provider independent. I don't have a problem with hibernate at all, I will go on using it since it's just great, but the question just came up in my head and I wanted to know if you maybe already discussed something like that with the jpa team?
