SAP Cloud Integration is built upon the Apache Camel integration framework. It utilizes Apache Camel's Simple Expression Language as the standard way to access and manipulate message content, including headers, properties, and the message body, within various integration flow steps. This language uses a straightforward ${...} notation to dynamically retrieve values at runtime. For example, ${header.myHeader} accesses a message header named 'myHeader', and ${property.myProperty} accesses an exchange property.

A. JavaScript is a scripting language used within a dedicated Script step for complex transformations, not the standard expression language for component configuration.

B. "XML expression language" is not a standard term. While XPath is used specifically for navigating XML documents, Simple language is for general message access.

C. SAP Cloud Integration does not expose the Spring Expression Language (SpEL) for developers to use in integration flow components.
