The "outTransformElements", "inTransformElements", "outDropElements", "inDropElements", "outAppendElements", "inAppendElements" and "attributesAsElements" properties can be used.

On the outbound service side, some of the transformation features (e.g. "outTransformElements", "outDropElements") may not work properly prior to CXF versions 3.2.6 and 3.1.17. This is due to outputstream optimization that CXF does. In this case, the outputstream optimization must be explicitly disabled for the outbound transformation feature to work properly by setting the JAX-WS/JAX-RS property "disable.outputstream.optimization" to "true".

Replacing text content

It's possible to replace the text content of a given simple element only on the input and output, for example:
