But there there should be no room for debate, one side is right and the
other side is wrong. If there is really a grey area, the solution is to
fix the wording of the standards document, not to try and overlook the
problem.

I agree that in this case it is possible to have ignored the bad AS PATH
and drop the route without disturbing the session originating the bad
information. This is one specific example could probably have been handled
better with a non-fatal notification (with big red lights and buzzers).
However, it was unacceptable for that router to propagate the bad
information to others.
