The idea of XML, and of *separating* markup from format, predates
both HTML and CSS. (And note how the required "alt" attribute of the
HTML "img" tag is rendered by many browsers...)

Usually, a style sheet and an XML document instance _are_ separate,
they can be combined freely using one processing instruction.

: <issue-date><year>2003</year><month>4</month><day>31</day></issue-date>

If, for some reason (other than related to rendering), you need to
transform your data into the line above (and not into HTML for rendering),

  <xsl:template match='issue-date'>
    <issue-date>
      <year><xsl:value-of select='@year'/></year>
      <month><xsl:value-of select='@month'/></month>
      <day><xsl:value-of select='@date'/></day>
    </issue-date>
  </xsl:template>

(If the source and destination names "year", "month", "day", are known
to stay, you could even reuse the attribute names for element names.)
