Comment 8 for bug 100620

re: the cons:

We could look, in the trunk, at changing the way services are looked up. I think recent versions of Five would let us do this in the Zope 3 way, looking them up by interface. (not 100% sure) This would be an improvement over acquisition based look up, but it would require some changes to the core and most extensions, so if we want to do this, most likely we would need to do it in the context of a project that benefits from it.

xx I don't really understand. You mean the tales expression is evaluated during export, and whether that is a problem? I should be able to test this relatively easily, since I probably have the most intimate knowledge of the xml export/import system, so if you have an idea of how to implement this part of the behavior for testing on a branch without spending too much time, I suggest you do it and let me know, and I can look at possible implications.
