[dwbp] Freezing the document

Hi group,

Thanks for your contributions!
We have made a lot of changes (they are summarized on the change history) on the document [1] and we’re happy to freeze the document and let you review it.

The last version of the document will be frozen until our next meeting.

cheers,
Berna, Carol and Newton.
