Chuck, it is actually in the CAFIB standard:
2. Temperament
It is a courageous, determined and daring dog.
It does not hide its aversion to strangers, or its traditional tenderness to its
owners and family. Consequently, it is an unsurpassed watch dog in the cities,
and an excellent herding dog and a hunter of big animals on farms. As a result
of its temperament, at dog shows it does not allow the judge(a stranger) to
touch it. And if it attacks the judge, such a reaction must not be considered a
fault, but only a confirmation of its temperament. At temperament tests,
obligatory for dogs over one year old at shows, the Fila attack must be in an
ascending diagonal, in front of handler and without showing dependence from him.
