Your stylesheet is correctly displaying the string-value of the <Text/>
element. The string value of the <Text/> element is the concatenation of all
its descendant text nodes. Since there are no descendant text nodes, the
string-value is the empty string, "". Perhaps you meant <xsl:copy-of>
instead of <xsl:value-of>?
