SOAPFactoryImpl forces namespace declarations to be added for all child elements which are not immediate descendants of the element declaring the namespaces. This is seen in ESB as a consequence of adding a Document to the soap body.

For example

<say:sayHiResponse xmlns:say='http://www.jboss.org/sayHi' xmlns:say2='http://www.jboss.org/sayHi2'>
<say2:arg0>
<say2:arg2>Response</say2:arg2>
</say2:arg0>
</say:sayHiResponse>

will be created as

<say:sayHiResponse xmlns:say='http://www.jboss.org/sayHi' xmlns:say2='http://www.jboss.org/sayHi2'>
<say2:arg0>
<say2:arg2 xmlns:say2='http://www.jboss.org/sayHi2'>Response</say2:arg2>
</say2:arg0>
</say:sayHiResponse>
