Not by trying to update a variable, that's not the way XSLT works.

Do it like this:

<xsl:variable name="commentVar">
  <xsl:for-each select="Header">
    <xsl:value-of select="Comment"/>
  </xsl:for-each>
</xsl:variable>

<Comments>
  <xsl:value-of select="$commentVar"/>
</Comments>

Of course, you might not need a variable at all, you can just do the
xsl:for-each inside the <Comments> element.

In XPath 2.0 / Saxon 7.0, you can just do:

<Comments>
  <xsl:value-of select="Header/Comment" separator=""/>
</Comments>
