I don't think so here--I don't believe either fo:s-p-m or fo:region-body generate reference areas--indeed, I don't think anything located outside of fo:page-sequence does. The spec says they are *used* to create a reference area, but they don't generate one themselves. So maybe your calculations here may need changing--because different formulae in 5.3.2 would hence be activated. Section 6.1 [1] says "There are three kinds of formatting objects: (1) those that generate areas, (2) those that return areas, but do not generate them, and (3) those that are used in the generation of areas." fo:s-p-m and fo:region-body are type (3), not type (1). fo:s-p-m text: The fo:simple-page-master formatting object generates no area directly. It is used in the generation of pages by an fo:page-sequence. type (3) fo:r-b text: The fo:region-body formatting object is used to generate one region-viewport-area and one region-reference-area whenever an fo:simple-page-master that has an fo:region-body as a child is used to generate a page. (i.e., type 3) [1] http://www.w3.org/TR/2001/REC-xsl-20011015/slice6.html#fo-section > So in your case you could specify > a margin="0pt" on > the region-body which triggers the first formula > given in 5.3.2. Again, I don't think so because fo:region-body never generates a reference-area. Hence, with no explicit specification of margin properites, the third set of formulas then activates: margin-corresponding = start-indent - inherited_value_of(start-indent) - padding-corresponding - border-corresponding-width with the additional rule that: "If the "start-indent" or "end-indent" properties are not specified their inherited value is used in these formulae." Since start-indent and end-indent were not specified, then we have: margin-corresponding = inherited_value_of(start-indent) - inherited_value_of(start-indent) - padding-corresponding - border-corresponding-width, or zero for the margin properties on fo:region-body. (i.e., we just rely on the 50pt. on simple-page-master.) So Luca is correct that both fo:simple-page-masters should generate the same overall margins of 50 pt. each, no? Thanks, Glen
