XML Schema is a language used to define the structure, content, and data types of XML documents. It provides a set of rules and constraints for validating XML documents against a predefined schema definition. XML Schema includes elements for defining complex data types, enumerations, constraints, and relationships between elements to ensure the consistency and integrity of XML data exchanged between systems. XML Schema is commonly used in web services, data interchange formats, and XML-based applications for data validation and interoperability.
