Re: [xsl] function returning string with string-join()

[Michael Kay <mike@xxxxxxxxxxxx>]

The variable is a document node, so there's no need for the 
string-join(), or even string(), to convert it to a string, it will 
happen automatically.

I'd be tempted to do:

<xsl:function name="my:filename" as="xs:string">
  <xsl:param name="input" as="xs:integer" />
  <xsl:value-of>
    <xsl:choose>
      <xsl:when test="$input eq 1">NO1</xsl:when>
      <xsl:when test="$input eq 2">NO2</xsl:when>
      <xsl:otherwise>NOx</xsl:otherwise>
    </xsl:choose>
    <xsl:text>.html</xsl:text>
   </xsl:value-of>
</xsl:function>
