You might want

   <xsl:variable name="dummy"
 
select="ArrayOfBookMark/BookMark[ShortName='Asp-7041-EndVar1]/Value"/>
   <xsl:variable name="dummy1"
                 select="if ($dummy) then $dummy else '$'"/>

That is XSLT 2.0 supported by Saxon, Altova, Gestalt.

If you use XSLT 1.0 then it is more difficult:

   <xsl:variable name="dummy"
 
select="ArrayOfBookMark/BookMark[ShortName='Asp-7041-EndVar1]/Value"/>
   <xsl:variable name="dummy1">
     <xsl:choose>
       <xsl:when test="$dummy">
         <xsl:value-of select="$dummy"/>
       </xsl:when>
       <xsl:otherwise>$</xsl:otherwise>
     </xsl:choose>
   </xsl:variable>
