itself is also an XML document, rather than using a self-contained syntax like a DTD. This facilitates users and developers, because they can use the same tool to process XML Schema and other XML information, rather than using special tools for Schema. Schema is easy to understand. anyone who understands XML syntax and rules can understand it immediately. The concept of Schema has been put forward for a long time, but W3C standards have only recently come out, and the corresponding application

responsibility allocation principle, the whole creation logic is concentrated in a factory class, it can create the class can only be considered beforehand, if you need to add new classes, you need to change the factory class.
