Proposed Disposition of DIS 29500 Comment CZ-0055 (Modified: 2007-12-05) Agreed; to make this clearer the following text will be appended to the paragraph in Part 4, §2.15.1.89, page 1,255, lines 67: This element specifies the language which shall be used to determine the appropriate theme fonts in the document’s Theme part which map to the major/minor theme fonts. Specifically, the bidi attribute is used to determine the theme font applied to complex script text, the eastAsia attribute is used to determine the theme font applied to East Asian text, and the val attribute is used to determine the theme font applied to all other text.
