No, it isn't.

Same problem for me.

Yes, I have. I'm currently working with the batik sources. The problem seems 
to be the URI resolving. Batik has an own version of it.
Currently I'm working on the transcoders of Batik. When this is done, I would 
work on the URL resolving problem. But I think my current work will take 
perhaps two weeks or more. So perhaps, you can take the other problem. Some 
java knowledge would be good for it. ;) I think the best would be to start in 
the Bridge code of batik (easy to find). It transforms the parsed SVG 
document into a SVG DOM tree. For every tag, including "image", there's a 
bridge class. From there you have to look for the URI resolving. I had found 
it very fast, but don't rember where it exactly was. This has to be modified 
for using the cocoon resolver. The problem is, that batik isn't based on 
avalon/ excalibur. So it could be some work. But then, you would have all URI 
features of cocoon avalaible. If you want to try it, feel free to ask me (but 
don't forget I'm a newbie to batik) or the batik developers mailing list.

I had the same problem.
