Close - but you want a key rather than a variable.

Declare the key outside of any template.

<xsl:key name="productNameByID" 
	match="info/produkte/produkt" 
	use="@id"/> 

This will let you "catch" nodes in the document that are matched
by the match expression, using their id attribute.

You use the key inside your for-each like so:
 <fo:block>
    <!--  <xsl:value-of select="@id"/>  -->
	<xsl:value-of select="key('productNameByID',@id)/@bezeichnung"/>
   </fo:block> 

Keys also speed things up considerably and are used for grouping.

Have fun.
