Proposed Disposition of DIS 29500 Comment IL-0030 (Modified: 2008-01-13) Agreed; description of readingOrder does not specify the effect of the three values on text alignment in cells. We propose an update to the specification as shown below, and note that context dependent reading order is necessarily different than Unicode, in order to support formulas in SpreadsheetML. Because formulas begin with non-strong characters and must be written left-to-right, SpreadsheetML determines the reading order based on the first non-whitespace character. The following change will be made to the table in Part 4, §3.8.1, pages 20922093: Attributes Description readingOrder (Reading Order) An integer value indicating whether the reading order (bidirectionality) of the cell is left-to-right, right-to-left, or context dependent. 0 - Context Dependent - reading order is determined by scanning the text for the first non-whitespace character: if it is a strong right-to-left character reading order it set to right-to-left; otherwise, the reading order is set as left-to-right. 1 - Left-to-Right - reading order should move left-to-right in the cell, as in English. 2 - Right-to-Left - reading order should move right-to-left in the cell, as in Hebrew. The possible values for this attribute are defined by the XML Schema unsignedInt datatype.
