RE: flow direction

Thanks!

it correctly flows on the second page, perfect!
I now realize that my page-sequence-master is wrong as the TOC gets a
strange empty layout (no header and no footer), while I would expect it
to use simple-page-master named "main":

<fo:page-sequence-master master-name="content">

  <fo:repeatable-page-master-alternatives>
      <fo:conditional-page-master-reference
         page-position="first" master-name="first"/>
      <fo:conditional-page-master-reference
         page-position="rest"  master-name="main"/>
  </fo:repeatable-page-master-alternatives>

</fo:page-sequence-master>
