I tend to agree with Manlio from an end user perspective. It's a case of
"do not feed the elephant". Seeing this sign, what do you do if there is no
elephant around? "Do not feed the elephant in the cage" doesn't change the
situation if there is neither elephant nor cage... :-)

(Obviously from a developer perspective, I appreciate you might need extra
code to not fail on resolving non-existing schemas. And I guess this is not
a very high priority issue...)
