Which protocol provides a structured model for messaging, based on XML, for web services?

Explanation:
SOAP provides a formal, XML-based message model for web services. It defines a strict envelope structure with elements like Envelope, Header, and Body, and uses Fault to signal errors. This ensures messages are packaged with metadata and a predictable format, enabling reliable, interoperable communication across different platforms. REST is an architectural style that doesn’t mandate XML or a fixed envelope, XML-RPC uses XML but lacks the full envelope-oriented standard of SOAP, and JSON-RPC uses JSON. The XML-based, envelope-centered messaging discipline is characteristic of SOAP, making it the correct choice.
