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.
