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

[Michael Müller-Hillebrand <mmh@xxxxxxxxxxxxx>]

Hello experts,

I find myself building functions like this (no real code!) to return a
string:

<xsl:function name="my:filename" as="xs:string">
  <xsl:param name="input" as="xs:integer" />
  <xsl:variable name="strings">
    <xsl:choose>
      <xsl:when test="$input eq 1">
        <xsl:value-of select="'NO1'" />
      </xsl:when>
      <xsl:when test="$input eq 2">
        <xsl:value-of select="'NO2'" />
      </xsl:when>
      <xsl:otherwise>
        <xsl:message select="'otherwise?'" />
        <xsl:value-of select="'NOx'" />
      </xsl:otherwise>
    </xsl:choose>
    <xsl:value-of select="'.html'" />
  </xsl:variable>
  <xsl:value-of select="string-join($strings, '')" />
</xsl:function>

In a variable this builds a sequence of strings using individual xsl:value-of
and in the end they are joined. Is this the way to do it if I cannot concat()
everything in a single, large xsl:value-of?

I have a feeling that it might be simpler?

Thanks for teaching me new/old tricks :-)
