Description
Define the return value for a function. The value can be a simple scalar value, an XML element or XPath expression, or a set of instructions that emit the value to be returned.
SLAX Example
The following example defines three extension functions, my:size(), my:box-parts(), and my:ark(). The my:ark() function returns a node set containing an <ark> element that encloses the node set returned by the my:box-parts() function. The my:box-parts() function returns a node set containing a <box> element enclosing three <part> child
elements. The content of each <part> element is the value returned by the my:size() function. The return value of the my:size() function is the product of the three parameters width, height, and scale.

version 1.1;
ns my exclude = "http://www.example.com/myfunctions";
function my:size ($x, $y, $scale = 1) {
result $x * $y * $scale;
}
function my:box-parts ($width, $height, $depth, $scale = 1) {
result <box> {
<part count=2> my:size($width, $depth);
<part count=2> my:size($width, $height);
<part count=2> my:size($depth, $height);
}
}
function my:ark () {
result {
<ark> {
copy-of my:box-parts(2.5, 1.5, 1.5);
}
}
}

var $res = my:ark();
