public class XdmFunctionItem
The class XdmFunctionItem represents an item in an XPath 3.0 sequence
that represents a function.
Note that there is no guarantee that every XdmValue comprising a single
function item will be an instance of this class. To force this, use the Simplify
property of the XdmValue.
At present the only way of creating an instance of this class is as the result of an XPath or XQuery expression that returns a function item. Note that this feature requires XPath 3.0 or XQuery 3.0 to be enabled, which in turn requires use of Saxon-EE.
