                Static value for the attribute or property.
                Static attribute values. The values in this element should be
                assigned to the account as-is.
                List of values for the attribute provided in an appropriate XML elements
                that specify attribute name. (as is usual for properties)
                Only one attribute may be specified here, although it may have multiple
                values. Multi-valued attributes are expressed by repeating the same XML
                element multiple times.
                Hence all the XML elements that match this xsd:any must have the same
                element names (may have different values of course).
                Please note that this is nillable and therefore it may be
                explicitly set to "nil" value. Doing this means that empty
                set of values should be constructed. E.g. setting
                this to "nil" and also setting "authoritative" flag
                may enforce removal of all attribute values (if used properly).
