W3C XML Schema

W3C XML Schema is a set of guidelines used to define the structure of XML documents. Think of it as a blueprint that specifies what elements (like tags) and attributes (properties) must be present, how they relate to one another, and what type of data they can contain. This ensures that XML files are consistent and valid, making it easier for software to read and process the information. By using XML Schema, developers and organizations can create standardized data formats that enhance communication and data exchange between different systems.
