XML Nodes to be inserted with XSLT in a second Stylesheet

I have to insert some complete nodes with child nodes an all the attributes of these nodes from an XML file into a second XSLT Stylesheet, I want to create with the first one.

This is an example for the XML:

<?xml version="1.0" encoding="UTF-8"?>
<data xmlns:xsl="http://ift.tt/tCZ8VR" version="1.0" 
      xmlns:fo="http://ift.tt/vyPH5E"
      xmlns:xslout="it's replaced to xmlns:xsl within the transformation">

    <text-german>

        <fo:block font-weight="bold" space-after.optimum="10mm">
            Ihr Coupon
        </fo:block>
        <fo:block space-after.optimum="10mm">
            <xsl:text>Guten Tag </xsl:text>
            <xslout:value-of select="givenname"/>
            <xslout:text> </xslout:text>
            <xslout:value-of select="surname" />
            <xslout:text>,</xslout:text>
        </fo:block>
        <fo:block space-after.optimum="5mm">
            <xslout:text>Some text...</xslout:text>
            <xslout:value-of select="issuerLong" />
            <xslout:text>Here more text...</xslout:text>
        </fo:block>
        <fo:block>
            <fo:inline font-style="italic">
                <xslout:text>Coupon: </xslout:text>
            </fo:inline>
            <fo:inline font-weight="bold">
                <xslout:value-of select="code" />
            </fo:inline>
        </fo:block>
    </text-german>

</data>

I want to insert all the content of the node <text-german> into the Output. Before, I have tried to do this with the command <xsl:value of select="text-german"/>, but this does only affect the content of this specific node, not the inherited child nodes with their content and thier attributes.

How do I insert all the content of the node in my output file?

For better understanding here the text i want to have in my output:

<fo:block font-weight="bold" space-after.optimum="10mm">
    Ihr Coupon
</fo:block>
<fo:block space-after.optimum="10mm">
    <xsl:text>Guten Tag </xsl:text>
    <xslout:value-of select="givenname"/>
    <xslout:text> </xslout:text>
    <xslout:value-of select="surname" />
    <xslout:text>,</xslout:text>
</fo:block>
<fo:block space-after.optimum="5mm">
    <xslout:text>Some text...</xslout:text>
    <xslout:value-of select="issuerLong" />
    <xslout:text>Here more text...</xslout:text>
</fo:block>
<fo:block>
    <fo:inline font-style="italic">
        <xslout:text>Coupon: </xslout:text>
    </fo:inline>
    <fo:inline font-weight="bold">
        <xslout:value-of select="code" />
    </fo:inline>
 </fo:block>
