ulink.hyphenate.chars — List of characters to allow ulink URLs to be automatically hyphenated on
If the ulink.hyphenate is not empty, then
hyphenation of ulinks is turned on, and any
character contained in this parameter is treated as an allowable
hyphenation point.
The default value is “/”, but the parameter could be customized to contain other URL characters, as for example:
<xsl:param name="ulink.hyphenate.chars">:/@&?.#</xsl:param>
