For example I use the following to avoid a pagebreak for sections in my preface chapter for pdf:
<xsl:attribute-set name="section.level1.properties">
<xsl:attribute name="break-after">
<xsl:choose>
<xsl:when test="ancestor::preface/@role = 'preface'">auto</xsl:when>
<xsl:otherwise>page</xsl:otherwise>
</xsl:choose>
</xsl:attribute>
</xsl:attribute-set>
If I put this into my customizing layer for epub it appears to have no influence.
Best regards, Lars
