Hi folks!

Today I'm working on countersignatures, and I'm having a problem with
xmlsec not finding an element with Id= that is cited in the URI= of a
<ds:Reference>:

Error: signature failed
Error: failed to sign file "extSigned2.xml.raw"


The extSigned2.xml.raw file is found in the attached ZIP file, named
".zzz" to get past mail filters.

That file was successfully signed with a <ds:Signature> that has a
<ds:SignatureValue Id="addedSigVal"> signature value.

To again sign the document and this time also countersign that first
signature, I'm adding a second <ds:Signature> that has two
<ds:Reference> elements: the first one points to the document using
URI="", and the second one points to the signature value of the first
signature using URI="#addedSigVal".

The first line of the error message above indicates that the element
with the id "addedSigVal" cannot be found.

I get the same message if I try to point to the first <ds:Signature>
using URI="#addedSig".

Is this enough information to determine if the software is wrong or if
I'm asking too much?

Thanks!
