Giuseppe -

Thanx for the review.

A WG member has filed an appeal to the IESG regarding WG last call consensus on this document. 
Authors have decided to wait for that appeal process to complete before resuming work on the document.

Once that process completes, we will (if still appropriate) resume work on the document - at which time we will review and respond to your comments.

Thanx very much for your patience.

    Les
