从Java类或XML创建XSD？

Question

将来，从Java Class或Xml获取XSD文件以验证XML文件的最佳方法是什么？

Answer 1

Neither. It's best to create an XSD by careful deliberation by hand.

Automatically creating an XSD from an object or an XML document instance can be useful to jumpstart the process but cannot capture all constraints likely to be needed. Consider that in general, a single member of a category rarely possesses sufficient characteristics to support basing the definition of the entire category on it alone.
