We need 0 for printers that support passwords but do not require them...

Ideally we'd want a rangeOfInteger(0:MAX) value to provide minimum and maximum lengths - not sure how much trouble we'd cause by extending that attribute to "integer(0:MAX) | rangeOfInteger(0:MAX)", but IMHO that would be the ideal outcome.
