/// either through the set() method directly, or via an element handed to the decode() method.
/// The decode() method expects an \<optionslist> element with one or more children. The child names
/// match the registered name of the option and have up to three child elements, \<param1>, \<param2> and \<param3>,
/// whose content is provided as the optional parameters to command.
