If you leave out the <arg position="0" name="message" key="submittedValue" resource="false"/>'s, there are no errors, you just see {0} in the message.
This happens when you do not pass any <arg position="0" name="parameter" key="submittedValue" resource="false"/>'s
Can we do a better job of error handling?

Solution: Add the missing the <formset><form> in custom-rules.xml
We should handle this better. Instead of the assertion, (or NPE if assertions are turned off) check for null and throw a descriptive error message.
