Use $local:function
Progress!
If I invoke the passed-as-a-parameter function as
<xsl:sequence select="$local:tiny('away')" />
in the stylesheet called by transform(), it changes the error.
<xsl:param as="function(xs:string) as text()" name="local:tiny" /> now
returns the error
Engine name: Saxon-EE 10.3 (External)
Severity: error
Description: A value must be supplied for parameter $local:tiny because there
is no default value for the required type
oXygen binds the error to the parameter definition in the called
stylesheet.
Putting a default value in the select attribute via an anonymous
function appears to override the passed-in function. It also gets
impractically complex for a non-toy-example function, so that can't be
right.
required="no" does not help. Removing the "as" attribute changes the
error to:
The required item type of the target of the dynamic function call is
function(*); the supplied value "" is an atomic value
so I conclude that I can't have the param rely on the definition of
whatever function gets passed to it.
Trying to search for "function parameter" gets the parameters of
functions, rather than this case, so I haven't been able to find an
example.
Thank you! being able to change the error produces hope.
