UBL Profile for XML Digital Signatures and XAdES implementation

Dear friends,

 

Here is the last iteration of the document.

 

In yellow is marked what I think needs further discussion.

 

Originally the reference  to the element <ds:Signature> in  <cac:Signature> was done through 
cac:DigitalSignatureAttachment/cac:ExternalReference/cbc:URI  using Id (unique
identifier) from  <ds:Signature>.

 

Now there are two references

-         
cac:Signature/cbc:ID using Id
(unique identifier) from  <ds:Signature>.

-         
cac:DigitalSignatureAttachment/cac:ExternalReference/cbc:URI 
using a  #xpointer to  ds:Signature

 

I think this adds complexity and I don´t understand why could be
useful. 

 

I have made a small change in the specification of
SignatoryParty

 

Originally it was stated that, being optional, if exists PartyIdentification,
its  cbc:ID must be signer  subjectDN . This is not bad. But other identifiers can exists, as an example, the issuer VAT
number.  

So, in this versión, if there are elements  PartyIdentification,
one must contain attribute  schemaID=”X509SubjectName” in  cbc:ID,
y (signer cert).

 

I foresee your comments.

 

Sorry for the delay.

 

Best regards,

 

Julián Inza
