The main goal of this task is the production of an ETSI TS on electronic signature format in XML, which will contain the XML syntax for qualified signatures equivalent to the ones specified in ETSI TS 101733. This task will take as starting point the technical report ?XML Electronic Signatures? produced by STF 155. The current W3C basic XML signature format is used to adopt the higher-level ETSI signature format to the XML world. This draft will be externally circulated in suitable forums (XML W3C Working Groups, XML/EDI groups, etc.) in order to harmonise with results and ongoing activities of those bodies.
