It's on my todo-list. When I'll have free time. You know
the song (I'm not sure this French expression exists in
English, but it could be understandable :-p).
For literals, since there are not so any base types
(although there could be a lot less) you can probably just
use xsl:choose, something like:
<xsl:function name="ns:func">
<xsl:param name="arg" as="node()"/>
<xsl:choose>
<xsl:when test="$arg instance of xs:integer">
<xsl:sequence select="ns:func-integer($arg)"/>
</xsl:when>
<xsl:when test="$arg instance of xs:string">
<xsl:sequence select="ns:func-string($arg)"/>
</xsl:when>
...
<xsl:otherwise>
<xsl:apply-templates select="$arg" mode="ns:func"/>
</xsl:otherwise>
</xsl:choose>
</xsl:function>
Yes, it's what I'm using now.
Thanks for the pointer,
