// Class TXMLSetup is used as storage of xml file settings
// This class is used in TXMLFile and in TXmlBuffer classes.
// Xml settings can be codded via a string in following format
//
// "2xoo"
// ||| \ .
// || \ usage of name spaces.
// | \ usage of DTD;
// \ storage of TStreamerInfo objects in file;
// layout of xml file (= 2 - specialized (default), = 3 - generic)
//
// For last three boolean parameters "x" means true, "o" - false
//
// Such string can be set as argument of TXMLFile constructor. In that
// case new TXMLFile with such parameters will be created.
// These settings automatically stored in xml file.
