Running cxf on a tomcat launched with the jvm argument "-Duser.language=fr".
Mtom and schema validation are enabled.
While sending a soap message, we have this error : "Wrapped by: org.apache.camel.RuntimeCamelException: org.apache.cxf.interceptor.Fault: Marshalling Error: cvc-type.3.1.2 : L'élément 'xxx' est de type simple et ne doit comporter aucun enfant ([children]) de type élément d'information."
Reason is a lack in the hack allowing validation with mtom enabled in org.apache.cxf.jaxb.io.DataWriterImpl.java.
In french, the colon is always separated with a space from the preceding word : "cvc-type.3.1.2 : "
I would reckon to just not include the colon anymore in the checking. It seams useless according to this documentation : https://wiki.xmldation.com/Support/Validator
Looking quickly on the code, some other hacks should not work in french in the sibling class DataReaderImpl.java.
I will submit a pull request during the week-end to correct this issue.
