Yes, I'd like to do this too. It's not easy though. If your stylesheet
does:

<xsl:variable name="temp">
  <files>
    <xsl:element name="{substring('field', 1, 4)}"/>

Then your code above might be perfectly legitimate. We aren't proposing
that every temporary tree must conform to a schema or DTD.
