Add additional <ds:Object> to Signature

[fmoessle]

Hi!

I currently have an issue adding an additional ds:Object to the signature.

  <ds:Object Id="document.xml">
    xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx</ds:Object>

It should contain a base64 encoded copy of the original XML document that is signed.

How can I do this with xadesjs?
