Differences Between DTD and XML Schema

When working with XML, it’s important to define rules that describe the structure and content of your documents. Two common ways to do this are DTD (Document Type Definition) and XML Schema (XSD). While both serve the same basic purpose, they differ greatly in features, flexibility, and modern usage.

DTD (Document Type Definition) and XML Schema (XSD) are both used to define the structure and rules of XML documents, but they differ significantly in power, syntax, and capabilities.
