Proposed Disposition of DIS 29500 Comment IL-0031 (Modified: 2008-01-04) Agreed; we will provide a better example for the descriptions of the RTL properties within each of attribute descriptions of the `rtl’ property. The change below should be made to the following parts: §5.1.5.2.2, page 3,383 §5.1.5.2.7, page 3,401 §5.1.5.4.13, page 3,458 §5.1.5.4.14, page 3,466 §5.1.5.4.15, page 3,475 §5.1.5.4.16, page 3,483 §5.1.5.4.17, page 3,492 §5.1.5.4.18, page 3,500 §5.1.5.4.19, page 3,509 §5.1.5.4.20, page 3,517 §5.1.5.4.21, page 3,526 Attributes Description rtl (Right To Left) Specifies whether the text is right-to-left or left-to-right in its flow direction. If this attribute is omitted, then a value of 0, or left-to-right is implied. [Example: Consider the scenario where the user wanted text to flow from right to left. That is within the bounding text box the first word would be right aligned with each additional word being written to the left of the previous while continuing to flow top to bottom. The DrawingML to describe this might be as follows. Consider the following example of a text body with two lines of text. In this example, both lines contain English and Arabic text, however, the second line has the rtl attribute set to true whereas the first line does not set the rtl attribute. <p:txBody> ... <a:p> Attributes Description <a:r> <a:t>Test </a:t> </a:r> </a:p> <a:p> <a:pPr rtl="1"/> <a:r> <a:t>Test </a:t> </a:r> </a:p> </p:txBody> <p:txBody> ... <a:p> <a:pPr rtl="1" .../> ... <a:t>Sample text...</a:t> ... </a:p> </p:txBody> end example] The possible values for this attribute are defined by the XML Schema boolean datatype.
