"Unlikely" in this case is in the order of "maybe once, on any one

team pointed out when we first considered this solution ourselves, if
that level of probability is an issue, you need to be worrying about
cosmic rays and quantum-level events in your XSLT code.

A little tangential, but when I was in ICL I remember some meetings with hardware engineers who were implementing an appliance that did relational joins. As software people, we found it very hard to stomach the idea that the algorithm they were using had a finite probability of producing wrong answers (due to accidental hash conflicts). But the hardware guys were quite unfazed by this: they knew that all their designs had a finite probability of producing wrong answers, and they were accustomed to calculating the probabilities and deciding whether they were within acceptable tolerances.
