Problem with bookmarks and page breaks in PDF-output

Hello,

according to Bob Stayton's "Using the XSLT Stylesheets" I do the 
following to start every <sect1> on a new page.

<!-- force page break before sect1 -->
<xsl:attribute-set name="section.title.level1.properties">
   <xsl:attribute name="break-before">page</xsl:attribute>
</xsl:attribute-set>

But now the PDF bookmarks are incorrect (as viewed in Acrobat Reader): 
When a <sect1> starts on page N, the bookmarks links to page N-1.

I am using stylesheets 1.60.1 and XEP 3.3.

Greetings,
Joachim
