### Partial Applications
Dynamic function applications using `f:apply` are partially applied if
the number of arguments provided is less than the arity of the target
function.
function. For convenience, the `apply-gen` stylesheet will also
generate functions to perform partial application without the use of
`f:apply` for the first call, as in the first example below:
```xml
<!-- produces a new dynamic function of arity 5 - 3 = 2 -->

<!-- does the same, the long way -->
<variable name="partial-long"
select="f:apply( my:arity5(), 1, 2, 3 )" />
<!-- consequently, currying is supported -->
