Discussion: Since the meeting in Amsterdam the document had been slightly changed regarding the wording.

This was done by helpful guidance from the standards secretary. The work was not completely finished during the meeting, however, standards secretary M. Yonge kindly offered his help to complete the final formatting of the draft which was acknowledged by the working group. It is expected that the document will reach PWD status before the next meeting.
