Creating marginalia using side floats There is a wide used practice to place some notes on margins synchronized with the reference points in the main text, its known as "marginalia". To create marginalia in XSL FO you can use fo:float elements together with margin property. XSL FO Recommendation, Chapter 6.10.2 "fo:float" There are two page sequences below. First one (pages 2, 3) has a left-aligned marginalia created with 'start' floats. This page sequence utilize 'regular' page-master and it's flow has start-indent value big enought to accomodate float: <fo:flow flow-name="xsl-region-body" padding="6pt" start-indent="120pt"> All fo:float elements in this flow have zero indents and contain fo:block-container with fixed width of 100pt: <fo:float float="start" start-indent="0pt" clear="both"> <fo:block-container width="100pt"> <fo:block>Marginalia float</fo:block> </fo:block-container> </fo:float> As a result we will have a 100pt wide marginalia at the left side of the page. While such a 'one side' marginalia is very usefull indeed, it's a common requirement to place a marginalia on different sides of the page depending on its parity. Unfortunately this cannot be done by the means of strict XSL FO, but RenderX XEP allows you to create such an effect using special values of float property: inside and outside. Former will align floating block to the inner edge of the page (left for odd pages, right for even pages) and latter will align floating block to the outer edge of the page (right for odd pages, left for even pages). Second page sequence below (pages 4, 5) demonstrates creation of "duplex" marginalia aligned to the outer edge of the page, it's created using outside value of float property. This page sequence utilize a special pagemasters with negative margin on the start (left) side for odd pages and negative margin on the end (right) side: <fo:simple-page-master master-name="page-odd" margin="0.2in"> <fo:region-body margin="20pt 20pt 20pt -100pt"/> </fo:simple-page-master> <fo:simple-page-master master-name="page-even" margin="0.2in"> <fo:region-body margin="20pt -100pt 20pt 20pt"/> </fo:simple-page-master> <fo:page-sequence-master master-name="marginalia-duplex"> <fo:repeatable-page-master-alternatives> <fo:conditional-page-master-reference master-reference="page-odd" odd-or-even="odd"/> <fo:conditional-page-master-reference master-reference="page-even" odd-or-even="even"/> </fo:repeatable-page-master-alternatives> </fo:page-sequence-master> and it's flow has an appropriate start-indent and end-indent values: <fo:flow flow-name="xsl-region-body" padding="6pt" start-indent="120pt" end-indent="120pt"> Floats used in this flow look like this: <fo:float float="outside" start-indent="0pt" end-indent="0pt" clear="both"> <fo:block-container width="100pt"> <fo:block>Duplex marginalia float</fo:block> </fo:block-container> </fo:float> Simplex marginalia Lorem ipsum dolor sit amet, consetetur sadipscing elitr, sed diam nonumy eirmod tempor invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua.
