Description

I created a custom dataformat and call it with the XML-IO DSL like this:

    <unmarshal>
      <custom ref="myCustomDataformat"/>
    </unmarshal>

I get the following error:

org.apache.camel.xml.io.XmlPullParserException: Unexpected element '{}custom'

According to the XSD I would expect the custom element to be available

https://camel.apache.org/schema/spring/camel-spring-3.14.3.xsd

Also in Camel in Action2 (page 340) there is an example of this.

 

I load the XML with the "xml-io" library and "dataformat" is also on the classpath.

On the documentation page:

https://camel.apache.org/components/3.14.x/dataformats/index.html

The 'custom' dataformat isn't listed however and there is no documentation of it. Is it still supported?

Complete stacktrace:
