You should first get your signature converted into the proper DOM nodes,
then attach that as a child.
When JAXB marshals a DOM tree as sub-elements, it preserves all the
namespace declarations.
Since XML signature is very sensitive to the slightest change in the
infoset, binding XMLDsig schema to JAXB for the purpose of producing a
signature is a bad idea.
