Dear Juan Carlos,

we have other suggestions to extend XAdES schema.

In some cases metadata, attributes of toBeSigned files can be important. At
enveloped signature these attributes can be placed into the tag under the
root element, but in other cases (enveloping, detached) the only choice is
DataObjectFormat, but this element contains only Description,
ObjectIdentifier, MimeType and Encoding. Some other attributes that are also
defined in CMS or S/MIME standard should be implemented in XAdES schema such
as filename, creation-date, size (in Content-Type,
Content-Transfer-Encoding, Content-Description Content-Disposition etc.).

Insertion of these attributes into XAdES schema would be really helpful for
software developers to implement interoperable applications.

Best regards,
Aron Szabo
