  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.
