Reference to unsupplied parameters - I was thinking of the treatment
of unsupplied parameters in template definitions - which mitigate
against partial applications.

Sorry I meant partial application and you must forgive my syntax
because I have no idea what it should be but in

<xsl:variable name="f" as="function(xs:integer, xs:integer) as
xs:integer" select="1"/>

if  the function in the above variable is a function that adds two
integers then $f(3) returns 4 (i.e $f becomes a function that
increments it's argument by 1).
