      • atomize

        public Value atomize​(NodeInfo node)

        Parameters:
        sub - the other type (the type that is derived by restriction, validly or otherwise)
        Returns:
        null indicating that this type does indeed subsume the other; or a string indicating why it doesn't.

If there is no such attribute use, return null. If the fingerprint matches an attribute wildcard, return the type of the global attribute declaration with the given name if one exists, or AnySimpleType if none exists and lax validation is permitted by the wildcard.
        Specified by:
        getAttributeUseType in interface ComplexType
