-<para>If the <parameter>ulink.hyphenate</parameter> parameter is not
-empty, then hyphenation of ulinks is turned on, and any character
-contained in this parameter is treated as an allowable hyphenation
-point. This and <parameter>ulink.hyphenate</parameter> work together,
-one is pointless without the other being set to a non-empty value</para>
-
-<para>The default value is <quote>/</quote>, but the parameter could
-be customized to contain other URL characters, as for example:</para>
