For everybody involved, please read the above again.

Most people object to repotags because the repotag does not have any use 
in the version comparison. That's right, it does not.

But it *does* affect dependencies when there is no identifier in the 
version/release information. Particularly when there is more than one 
repository.

So it is indisputable that it is meaningful in the version information, 
because without it RPM would fail to resolve dependencies in a correct 
way.

This was brought up at least 3 times in the previous discusisons. You see 
why it is frustrating when people keep on objecting but loose half of the 
information that was provided. Why we have to repeat. Why Axel gets tired.
