+To help decide whether the change is a regression, and therefore
+should be Priority-Critical, please adopt the following process:
+
+@enumerate
+
+@item
+Are you certain the change is OK? If so, do nothing.
+
+@item
+Are you certain that the change is bad? Add it to the tracker
+as a Critical issue, regression.
+
+@item
+If you're not certain either way, add it to the tracker as a
+Critical issue, regression but be aware that it may be
+recategorised or marked invalid.
+
+@end enumerate
+
+In particular, anything that breaks a regression test is a
+regression.
