Based on the samples you've provided, the other group needs to provide a
little more information in the document containing the signature. Since it's
too much to type, I strongly recommend finding a copy of ".NET Framework
Security" from Addison-Wesley and looking at chapter 32 which has quite a
focus on XMLDSIG.
