4. Summary of Drafting Subgroup Meeting, March 11-13, Brussels
WLTP-10-34e
The content of those slides which were approved were integrated into the GTR.
Since the Brussels meeting, another 40 slides have been added to be processed.
The latest version of the GTR incorporating the results of the 3-day Brussels meeting was uploaded to the UN ECE server as:
WLTP-10-04e-GTR Version
This version contains all tracking changes, as they are necessary for the UN ECE Secretariat's work

5. Summary of Drafting Subgroup Meeting, March 11-13, Brussels
WLTP-10-34e
For the Drafting Subgroup and its work tomorrow, three documents have been uploaded to the UN ECE server:
The GTR, version including all tracking changes.
The GTR, version incorporating all GTR corrections (see next page), and material confirmed since the first days of the GTR. As a result, many tracking change bubbles have been eliminated, making the GTR more readable. This was requested during the Brussels meeting.
The 70+ slides mentioned on the previous page.

6. Summary of Drafting Subgroup Meeting, March 11-13, Brussels
WLTP-10-34e
Types of corrections incorporated into the GTR:
elimination of "must", use of the word "will", use of sample/samples/sampling/sampled, formatting, spelling, spacing, paragraph/equation/figure numbers were checked, use of weighing and weighting.
BTW: according to the UN ECE, "must" may not be used, only "shall". "Shall" is for obligations and "may" for options.
However, the GTR uses "must" on at least one occasion. These uses can be justified.
