I have an xslt template with 2 paramter. One of them must not be specified.
How can I find out if one or two params where specified? Do I need two versions of the template with mode? Or can I check with =''?
<xsl:template name="foo">
one mandatory paramter
one optional paramter
...do things...
</xsl:template>
One can call it by:
<xsl:call-template name="foo">
<xsl:with-param name=="bar_mandatory" select="$whatever" />
<xsl:with-param name="bar_optional" select="$whatever" />
</xsl:call-template>
OR
<xsl:call-template name="foo">
<xsl:with-param name=="bar_mandatory" select="$whatever" />
</xsl:call-template>
Rob
