For ulinks there are already two parameters how does URL breaking.

Did you already know the following parameters?

However, these apply to ulinks, not to filenames. Try the following:

1. Write a customization layer
2. Set hyphenation="false" to avoid any hyphenation
3. Call the named template "hyphenate-url" in your filename template. This
   template takes care of the appropriate location and inserts the character
   from the ulink.hyphenate parameter.

This snippet needs to be inserted into your customization layer: 

<xsl:template match="filename">
  <fo:inline hyphenate="false">
    <xsl:apply-templates mode="hyphenate-url"/>

The above template can be improved, but it's just the general idea.

Hope that helps,
