Subject: conditional page body with XSL-FO

Does anyone know if it is possible to have a conditional page body depending on whether or not the page is even or odd? I understand how to have conditional page-before and page-after (static content) styles. But I also want the body text (flow) to be formatted differently depending on whether or not the page is even or odd.

I attempted this by creating "body-even" and "body-odd" in the even and odd master sets. See below.

<fo:layout-master-set>


<fo:simple-page-master master-name="even" page-height="8.5in" page-width="5.5in>
<fo:region-body region-name="body-even" border="1pt solid black" display-align="before" margin-left="0.3125in" margin-right="0.75in" margin-top="0.5in" margin-bottom="0.5in"/>
<fo:region-before region-name="even-before" border="1pt solid black" display-align="before" extent="0.3125in"/>
<fo:region-after region-name="even-after" border="1pt solid black" display-align="after" extent="0.3125in"/>
</fo:simple-page-master>


<fo:simple-page-master master-name="odd" page-height="8.5in" page-width="5.5in">
<fo:region-body region-name="body-odd" border="1pt solid black" display-align="before" margin-left="0.75in" margin-right="0.3125in" margin-top="0.5in" margin-bottom="0.5in"/>
<fo:region-before region-name="odd-before" border="1pt solid black" display-align="before" extent="0.3125in"/>
<fo:region-after region-name="odd-after" border="1pt solid black" display-align="after" extent="0.3125in"/>
</fo:simple-page-master>

<fo:page-sequence-master master-name="chapter">
<fo:repeatable-page-master-alternatives>
<fo:conditional-page-master-reference master-reference="odd" page-position="any" odd-or-even="odd"/>
<fo:conditional-page-master-reference master-reference="even" page-position="any" odd-or-even="even"/>
</fo:repeatable-page-master-alternatives>
</fo:page-sequence-master>
</fo:layout-master-set>

<fo:page-sequence master-reference="chapter">
<fo:static-content flow-name="even-before">
<fo:block>
</fo:block>
</fo:static-content>
<fo:static-content flow-name="odd-before">
<fo:block>
</fo:block>
</fo:static-content>

<fo:static-content flow-name="even-after">
<fo:block>
<fo:page-number/>
</fo:block>
</fo:static-content>
<fo:static-content flow-name="odd-after">
<fo:block>
<fo:page-number/>
</fo:block>
</fo:static-content>

<fo:flow flow-name="body-odd">
"LOTS OF DATA HERE"
</fo:flow>
<fo:flow flow-name="body-even">
"LOTS OF DATA HERE"
</fo:flow>
</fo:page-sequence>

Hi Jerry,

My understanding is that you can create different layouts for odd/even pages and creates static text areas using the fo:static-conten; but the fo:flow for the region "body" is managed by the formatter that spans the content across pages.
