Which statement accurately describes SOAP web services?

Explanation:
SOAP web services rely on a formal contract described by WSDL, which is an XML-based language that defines the service interface—its operations, the input and output messages, and how clients bind to the service. The SOAP protocol itself uses XML to format the actual messages exchanged between client and server. So describing SOAP with an XML-based WSDL is accurate. REST, in contrast, does not use WSDL; it often uses JSON for payloads and is described by other formats like OpenAPI, not WSDL. HTML is not used to define REST rules.
