XML Calabash runs on the JVM and requires Java version 11 or later. It is implemented in Kotlin. It relies on the Kotlin runtime and on third party libraries for some functionality. In particular it was built with:

Saxon 12.x

XML Calabash 3.x is built on top of Saxon 12.5. There is no support for earlier releases of Saxon. It will work with Saxon HE, but you will have to provide Saxon EE and an appropriate license if you want to use licensed features (like XML Schema validation).

Some extension steps require additional dependencies. Those dependencies are documented with the extension steps.

If your pipelines don’t use features supported by third party libraries (for example, if you don’t have .br archives or convert MarkDown documents), you can omit the dependencies.

In many cases, you can use different versions of these libraries. For example, you can usually upgrade to more recent minor revisions. If the third party API has changed in some incompatible way, your pipeline will fail.
