BaseUsageValidationAttribute.Namespaces Property

Gets the namespaces that match the rule by identifying the namespaces by their full name. Any namespace string can contain one of the following patterns: (matches any identifier character, but not the dot), .. (matches any sub-namespace in the middle of a namespace), . (matches any sub-namespace at the beginning of a namespace) or .* (matches any sub-namespace at the end of a namespace -- this pattern is allowed but redundant).
