The sentence ‘or auto to allow a consumer to automatically determine the background color as appropriate.’ does not define the appropriate behavior of the consumer, whereas the definition of the corresponding simple type, found in Part 4, page 1737, explicitly states that ‘This value shall be used to specify an automatically determined color value, the meaning of which is interpreted based on the context of the parent XML element.’

Proposed change: Define the characteristics of the auto value for the color attribute of the background element properly.

Proposed Disposition of DIS 29500 Comment GB-0179 (Modified: 2007-11-29) Agreed; the following change will be made to Part 4, §2.2.1 on page 28: Attributes Description color (Background Color) Specifies the color for the background of the document. This color may either be presented as a hex value (in RRGGBB format), or auto to allow a consumer to automatically determine the background color as appropriate in order to make the document’s text readable. [Example: A document with white text and a background color of auto might result in the use of a black background, in order to ensure legibility of the content. end example] If the background specifies the use of a theme color via the themeColor attribute, this value is superseded by the theme color value. [Example: Consider a border background color with value 2C34FF , as follows: <w:background … w:color="2C34FF"/> The background color shall therefore be the color with an RGB value of 44,52,255 (the decimal decoding of the hex value above). end example] The possible values for this attribute are defined by the ST_HexColor simple type (§2.18.43).
