A function reference would be
local:get-string#2

Hello --

Using Saxon 10.3 and XSLT 3.0 (from inside oXygen 23), can I pass a function as
a parameter to transform()?

<xsl:sequence select="
transform(map {
'stylesheet-location': 'tidy.xsl',
'source-node': $tableMerge,
'stylesheet-params': map {
QName('', 'defaultLang'): $defaultLang,
QName('', 'overrideStringMap'): $overrideStringMap,
QName('', 'lang2key2autotextMap'): $lang2key2autotextMap,
QName('local','getString') : local:getString(xs:string,xs:string)
}
})?output" />

is syntactically acceptable.

Inside tidy.xsl,

<xsl:param as="xs:string" name="defaultLang" />
<xsl:param as="map(*)" name="overrideStringMap" />
<xsl:param as="map(*)" name="lang2key2autotextMap" />
<xsl:param as="function(xs:string,xs:string) as xs:string" name="local:getString" />

is syntactically acceptable (though oXygen complains about the actual function calls and not being able to find the function).

If I run the transform, though, I get:
Engine name: Saxon-EE 10.3 (External)
Severity: error
Description: An empty sequence is not allowed as the first argument of local:getString()

with a location that tells me the transform call parameter map is where the error happens.

Is there a way to do this? I can of course duplicate the function definition but that seems improper.

Thanks!
