/// derived class, which does the work of actually modifying the configuration. The command is issued
/// either through the set() method directly, or via an XML tag handed to the restoreXml() method.
/// The restoreXml() method expects an \<optionslist> tag with one or more sub-tags. The sub-tag names
/// match the registered name of the option and have up to three child tags, \<param1>, \<param2> and \<param3>,
/// whose content is provided as the optional parameters to command.
