A parameter may be supplied, which will return qualifiers of the required property, if they exist. If the value is set to a punctuation-separated list of property-IDs (e.g. P123, P456), then only the values of qualifiers with that property will be returned. If the value is set to , then all of the qualifier values are returned. If the value is set to then the and the of the property are returned with a date separator. In each case, any qualifier values returned follow the property value, and are enclosed in parentheses. If multiple qualifier values are returned, they will be separated by commas by default, although the separator can be changed by specifying (which may be enclosed in double-quotes, which are stripped out, so that spaces can be included). Setting the parameter will sort the returned qualifier values alphanumerically.
