Hi David,
You can define this behavior yourself by selecting a default value, i.e.:
<xsl:param name="routeValues" as="node()" select="$default/routeValues"/>
Or like so:
<xsl:param name="routeValues" as="node()" >
<default />
</xsl:param>
If you don't specify a default value, the empty sequence is returned, if
the as-attribute allows that.
Kind regards,
Abel Braaksma

Hi
In XSLT2, how should I test for null, or empty parameters? For example, if I have<xsl:param name="routeValues" as="node()?" /> how should I test whether a value has been passed, or whether it's empty?
Thanks
