To the folks who didn't use this:
Couldn't you use fo:keep-together.within-line="true"
http://www.w3.org/TR/xsl/#keep-together


Ron:

Here's a not very elegant solution I won't recommend:

Modify an inline.* template

  <!-- yeah, this should be reworked, it's just an example- ->
  <xsl:template name="inline.monoseq">
    <xsl:param name="no-hyphenate" select="false()"/>
    <xsl:param name="content">
      <xsl:apply-templates/>
    </xsl:param>
    <fo:inline xsl:use-attribute-sets="monospace.properties">
      <xsl:if test="@role[contains(., 'keep-together')]">
        <xsl:attribute name="keep-together.within-line">always</xsl:attribute>
        <xsl:attribute name="hyphenate">false</xsl:attribute>
      </xsl:if>
      <xsl:choose>
        <xsl:when test="$no-hyphenate">
          <xsl:attribute name="keep-together.within-line">always</xsl:attribute>
          <xsl:attribute name="hyphenate">false</xsl:attribute>
        </xsl:when>
        <xsl:otherwise>
              <!-- this is a zero-width space to intentionally provoke
an AntennaHouse bug.
                   The FO spec says that hyphenation-character can
only be on fo:block and
                   fo:character, but having anything her provides the
correct result. -->
          <xsl:attribute name="hyphenation-character">
            <xsl:value-of select="'&#x200B;'"/>
          </xsl:attribute>
        </xsl:otherwise>
      </xsl:choose>
       <xsl:when test="ancestor::footnote">
          <xsl:attribute name="font-size">90%</xsl:attribute>
        </xsl:when>
      </xsl:choose>
      <xsl:if test="@dir">
        <xsl:attribute name="direction">
          <xsl:choose>
            <xsl:when test="@dir = 'ltr' or @dir = 'lro'">ltr</xsl:when>
            <xsl:otherwise>rtl</xsl:otherwise>
          </xsl:choose>
        </xsl:attribute>
      </xsl:if>
      <xsl:copy-of select="$content"/>
    </fo:inline>
  </xsl:template>
