Juan Carlos,
You say:
"Imagine you send two documents. For the first one you define three
transformations: you want the server to generate three documents
(A1,A2,A3) and sign them. For the second you define two
transformations: you want the server to generate two documents
(B1,B2) and sign them. Now imagine you want A1,A2 and B2 enveloped;
B1 detached and A3 Enveloping the signature."
The last bit about "A3 Enveloping the signature" confuses me. I understand
how an InputDocument can envelope the signature. But you seem to be saying
the server would return the signature inserted into one of the
*post-transformed* Input Documents? I don't think that's what an Enveloped
Signature means in DSIG.
So when you say:
"Question: HOW TO EASILY IDENTIFY HERE THAT THE DOCUMENT THAT HAS
TO CONTAIN THE ds:Signature IS PRECISELY A3,. The most simple
answer: WELL; JUST INDICATE WITH AN INTEGER THE ORDER NUMBER
OF THE CORRESPONDING DocumentSelector!!. And yes, this would
work, but, at what price?"
I don't think A3 *will* contain the ds:Signature. The InputDocument that
was transformed to A3 will contain the signature. So you would want to
indicate with an integer the corresponding *InputDocument*, not
DocumentSelector.
Thus it doesn't make sense to associate a SignaturePlacementType with
DocumentSelector, as you propose. Do you agree?
