ISO TC36 RU Comments - C1 #1

4.1 ed The fragment “(x,y coordinates)” is irrelevant. Delete text in parenthesis

4.1 DCDM encoding primaries The DCDM shall use the CIE Publication15:2004 (x,y coordinates) to describe the color primaries X, Y, and Z as a gamut container.

Does 428-1 need to use a term other than "(x, y coordinates)"? For example, is that expression defined in a CIE document? Edit: the phrase "chromaticity coordinates" is defined in "CIE DIS 017/E:2016."

I do not see a reason to update the reference. There have been no changes. In fact it is now republished as an ISO doc, but the reference listed here is still readily found.

The fourth edition (2018) may be relevant for an LED reference projector document, but not for the use in this case.

As a new feature, the publication also includes further details of advanced colorimetry, including colour appearance models, and new findings on cone-fundamental-based tristimulus functions, with appropriate references to other CIE publications. Additionally, new illuminants for different LED types are introduced.

This publication is consistent with the fundamental data and procedures described in the CIE International Standards on colorimetry.

To satisfy RU del comment, DG agrees removing parenthetical does no harm, as per meeting 2/6/20.
