_Mike, can you impl your solution on top of Jason's proposal?_

Most likely. However, it's probably not something we could target in our own client CDI stuff. So if the {{@Before}} {{@After}} stuff was not standardized, we'd be forced to couple our stuff to a specific extension. That's the only downside for us. 

It seems to me that, while not necessarily a problem for the majority, we should strongly consider if this is a minority we should ignore. My opinion is that, while at any given time this is a minority problem, the majority will probably run into it at some point or another. 

My personal preference would be for _both_ an SPI and an standard for ordering in the programming model.

> There needs to be a way to specify some kind of ordering for Event observers. 
> Understandably, this is somewhat counter-intuitive to the general concept of observing an event, but there is going to be need for this in an upcoming JBoss project. While it can be done manually, it might be nice to have a built-in API.
