| Valid value | Description |
|---|
| before | The block-areas generated by the fo:float shall be with area-class "xsl-before-float", and shall be descendants of a before-float-reference-area generated by a conditional sub-region of a region-body. |
| start | The block-areas generated by the fo:float shall be with area-class "xsl-side-float" and shall be floated toward the start-edge of the reference area. |
| end | The block-areas returned by the fo:float shall be with area-class "xsl-side-float" and shall be floated toward the end-edge of the reference area. |
| left | Interpreted as "float='start'". |
| right | Interpreted as "float='end'". |
| inside | The block-areas returned by the fo:float shall be with area-class "xsl-side-float" and shall be floated toward an edge determined by the page binding edge. If the page binding edge is on the start-edge, it shall be floated toward the start-edge of the reference area. If the binding is the end-edge, it shall be floated toward the end-edge of the reference area. If neither, it shall be floated toward the start-edge of the reference area. |
| outside | The block-areas returned by the fo:float shall be with area-class "xsl-side-float" and shall be floated toward an edge determined by the page binding edge. If the page binding edge is on the start-edge, it shall be floated toward the end-edge of the reference area. If the binding is the end-edge, it shall be floated toward the start-edge of the reference area. If neither, it shall be floated toward the end-edge of the reference area. |
| none | The block-areas generated by the fo:float shall be normal. |
