I've analyzed a generic implementation using DOM to copy the namespaces but
due to lack of time to check performance impact I ended up with a faster
solution specific to my route. As I was using JAXB to unmarshal the XML in
a later moment I decided to unmarshal it earlier and split using simple
language.
The route became something like:
<route>
<from uri="..."/>
<unmarshal ref="jaxb-ctxt"/>
<split>
<simple>${body.collection.items}</simple>
<to uri="log:split-object"/>
</split>
</route>
The DOM solution did not seem hard to implement but it could impact
performance as any parent node may define (re-define) namespaces which
would be copied to 'n' nodes in the NodeList.
