Summary Proposal owner: Miklos Vajna Proposal short name: Bottom to top, left to right writing direction Rationale Use cases: Users sometimes want to have a text direction which is similar to latin text (left to right, then top to bottom), but rotated 90 degrees counter-clockwise. Also, this improves consistency, as doing the same in the clockwise direction is already possible (the top to bottom, right to left direction is used for e.g. Japanese text). Alternatives considered: It is possible to rotate characters at a span level, but that only gives similar result as long as the content fits a single line. Requested changes to the ODF Standard Text changes/additions (compared to ODF 1.2): 20.394.2 <style:graphic-properties> (existing section) Append to the end of style:writing-mode attribute value list: bt-lr. 20.394.3 <style:page-layout-properties> (existing section) Append to the end of style:writing-mode attribute value list: bt-lr. 20.394.4 <style:paragraph-properties> (existing section) Append to the end of style:writing-mode attribute value list: bt-lr. 20.394.5 <style:section-properties> (existing section) Append to the end of style:writing-mode attribute value list: bt-lr. 20.394.6 <style:table-cell-properties> (existing section) Append to the end of style:writing-mode attribute value list: bt-lr. 20.394.7 <style:table-properties> (existing section) Append to the end of style:writing-mode attribute value list: bt-lr. Schema changes/additions: <rng:define name="common-writing-mode-attlist">   <rng:optional>     <rng:attribute name="style:writing-mode">       <rng:choice>         <rng:value>lr-tb</rng:value>         <rng:value>rl-tb</rng:value>         <rng:value>tb-rl</rng:value>         <rng:value>tb-lr</rng:value>         <rng:value>lr</rng:value>         <rng:value>rl</rng:value>         <rng:value>tb</rng:value>         <rng:value>page</rng:value>         <rng:value>bt-lr</rng:value>       </rng:choice>     </rng:attribute>   </rng:optional> </rng:define> In other words, allow bt-lr as a new value of the style:writing-mode attribute. Impacts Conformance: This proposal will not add any mandatory features or behaviors. Backwards compatibility: This change will not impact existing ODF processors, the usage of the new attribute value is optional. Accessibility impact: This change will not impact accessibility. Interoperability: OOXML's wordprocessingML has a <w:textDirection w:val="btLr"/> markup to describe the same, this proposal allows roundtripping that feature in ODF. LibreOffice 6.3 implements this layout feature in its ODF extension namespace.
