Properties which are applied to every line in ToC (or LoT). You can modify them in order to change appearance of all, or some lines. For example, in order to make lines for chapters bold, specify the following in your customization layer:
<xsl:attribute-set name="toc.line.properties">
<xsl:attribute name="font-weight">
<xsl:choose>
<xsl:when test="self::chapter">bold</xsl:when>
<xsl:otherwise>normal</xsl:otherwise>
</xsl:choose>
</xsl:attribute>
</xsl:attribute-set>
