if it can be improved. Is there a way to write the function more idiomatic?
Shorter? Generalized to be more widely useful?  /Roger

Can't you simply process the tokens directly e.g.

  <xsl:for-each select="tokenize($line,
codepoints-to-string($line-delimiter))">
    <xsl:if test=". ne ''">
      <xsl:variable name="pos" select="position()"/>
      <xsl:element name="{$headers[$pos]}">
        <xsl:value-of select="."/>
?
