XML IDL

XML IDL, or XML Interface Definition Language, is a way to describe how different software components communicate using XML, a format that organizes data into a structured text format. It defines the rules and structure of messages exchanged between systems, ensuring they understand each other. Think of it as a contract that outlines what information can be shared and how, enabling interoperability between different programs or services. This is especially useful in web services, where various systems need to work together smoothly despite being built on different technologies.
