Dear all,

a new version of the Reducing Redundancy draft is now available. This version addresses all the comments received during last call. We believe that the draft has considerably improuved. Thanks to all who contributed and sent us feedback!

The structure has been changed, separating the description of the redundancy reduction technique from more advanced features such as multiple data reduction and cascaded common properties (new!) now both described in the "Advanced Techniques" section. The possibility to use templateId as an alternative to commonPropertiesId has been removed from the draft. Transport protocol considerations, reduced size encoding use recommendations and efficieny gain are part of the "Export and evaluation considerations".

Regards,
Elisa
