xsl:fo don't split word into 2 lines

Question

I want to stop splitting a generated word into two lines . Now I tried to use wrap-option="wrap" but nothing works. I hope some can help me ;)

I use Saxon-HE,xslt 2.0

My xml-file:

<root>
     <out>
          invidunt ut labore et dolore magna aliquyam erat, sed diam voluptua. 
          <build>
               <name>John</name>
               <year>29</year>
               <address>London</address>
               <code>12345678902331234313123123123123123123</code>
          </build>At vero eos et    
     </out>
</root>

My xslt-file:

 <xsl:template match="out">
        <fo:block>
               <xsl:apply-templates/>
        </fo:block>
    </xsl:template>

    <xsl:template match="build">
        <fo:inline wrap-option="wrap" color="Red">
            <xsl:value-of select="concat(./name,'-',./year,'-',./address,'+',./code)"/>
        </fo:inline>
    </xsl:template>

My expected output is following:

Invidunt ut labore et dolore magna aliquyam erat,sed diam voluptua
John-29-London+11231231231...

Output with my solution:

Invidunt ut labore et dolore magna aliquyam erat,sed diam voluptua John-29
-London+123123..

If those are the only templates in your stylesheet, text nodes are handled by the built-in template. You should not output text in such an uncontrolled way. If you add an empty template matching text() (as I have told you already), the text inside build appears on a single line.

XSLT Stylesheet

    <xsl:output method="xml" encoding="UTF-8" indent="yes" />

    <xsl:template match="/root">
      <fo:root>
        <fo:layout-master-set>
          <fo:simple-page-master master-name="page"
            page-height="297mm" page-width="210mm"
            margin-top="20mm" margin-bottom="10mm"
            margin-left="25mm" margin-right="25mm">
            <fo:region-body
              margin-top="0mm" margin-bottom="15mm"
              margin-left="0mm" margin-right="0mm"/>
            <fo:region-after extent="10mm"/>

    <xsl:template match="out">
        <fo:block>
               <xsl:apply-templates/>
        </fo:block>

    <xsl:template match="build">

            <xsl:value-of select="concat(name,'-',year,'-',address,'+',code)"/>
        </fo:inline>
    </xsl:template>

    <xsl:template match="text()"/>

But the real question is, how to prevent text from wrapping if it is actually longer than one line, e.g. if the input looked like

<code>123456789023312343131231231248364387438463846837483643123123123</code>

then, a well-placed keep achieves what you want:

<xsl:template match="build">
    <fo:inline keep-together.within-line="always" color="Red">
        <xsl:value-of select="concat(./name,'-',./year,'-',./address,'+',./code)"/>
    </fo:inline>
</xsl:template>

and then the line of text just overflows the page border

and finally, the keep-together, but without the template matching text():
