Title: how to build a valid XML Signature when the signature already exists

Dear,
How to do if the signature already exists (e.g stored as PKCS7 format on a backup system) ?? How to give the existing signature bytes, certificate, ... to the XML signature process ?

We have all elements in hands but we don't know how to proceed.
Sample code will be appreciated

Thanks a lot,
Philippe.
