> Seems I introduced a [bug|https://github.com/apache/camel/blob/master/camel-core/src/main/java/org/apache/camel/model/ModelHelper.java#L99] when implementing CAMEL-10509.
> If we're processing a namespace prefix of 'xmlns' then obviously we should not prefix it with the same value. But currently this is allowed and a namespace prefix of 'xmlns:xmlns' is added to the {{<routes>}} element. This can mean that the output from {{ModelHelper.dumpModelAsXml}} is invalid.
> However, I can only reproduce the problem on Karaf where the routes use xpath expressions. Some how with other platforms & scenarios the 'xmlns:xmlns' value is being ignored and never makes it into the {{dumpModelAsXml}} output.
