/WritingMode name
(Optional; inheritable) The directions of layout progression for packing of ILSEs (inline progression) and stacking of BLSEs (block progression): LrTb Inline progression from left to right; block progression from top to bottom. This is the typical writing mode for Western writing systems. RlTb Inline progression from right to left; block progression from top to bottom. This is the typical writing mode for Arabic and Hebrew writing systems. TbRl Inline progression from top to bottom; block progression from right to left. This is the typical writing mode for Chinese and Japanese writing systems. The specified layout directions shall apply to the given structure element and all of its descendants to any level of nesting. Default value: LrTb. For elements that produce multiple columns, the writing mode defines the direction of column progression within the reference area: the inline direction determines the stacking direction for columns and the default flow order of text from column to column. For tables, the writing mode controls the layout of rows and columns: table rows (structure type TR) shall be stacked in the block direction, cells within a row (structure type TD) in the inline direction. The inline-progression direction specified by the writing mode is subject to local override within the text being laid out, as described in Unicode Standard Annex #9, The Bidirectional Algorithm, available from the Unicode Consortium (see the Bibliography).
