No matter. I will assume that if >PassiveTeX's floats end up at the bottom of the page, no-one will >actually sue me. But bottom floats have issues such as whether they come before or after the footnotes. Top floats had the least issues and are probably (though I realize one could argue this) the most common thing to do. Note, you can float to the top of the next page--the spec doesn't say it has to float to the top of the current page. But it does say that specifically that float="before" means: that 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. The 1.0 spec does not define an xsl-after-float area-class, so while I would think it extreme for anyone to sue you, there doesn't seem to be a lot of room for thinking the spec allows for float="before" to end up at the bottom of the page in top-to-bottom writing modes. paul XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
