Why would you need an abstract advice? An advice is basically a
pointcut plus a method (which is not labelled!). If you want to make
yor pointcut abstract, you can do so. If you want to make the
implementation abstract, you can make the advice call an abstract
method.
You cannot declare the advice itself being abstract, simply because
it has no name, which implies that there would be no way to
implement/override it in a subaspect. AspectWerks uses plain Java for
notation of advice. There you can actually have such overriding. This
might however change due to the AspectJ/AspectWerkz merge.
