cool, thanks for the response, nice to know it worked out for you.

possibilities controlled by the new boundRemovedAction keyword argument:

Well... I'm not so sure about that. The thing is, many people don't
really care about the <bound> being preserved - well, I didn't care, for
example, till you reported the bug. And if the patch with the default
behavior of "fail" makes it into a new version of Osmosis, it will
suddenly break a lot of pipelines which have been working fine. So I'd
let it at a default "warn" for backward compatibility reasons if for

You're welcome :)
