An item is either an atomic value, a node, or a function item.
An item is a member of a sequence, but it can also be considered as a sequence (of length one) in its own right. XdmItem</ is a subtype of XdmValue</ because every Item in the XDM data model is also a value.
It cannot be assumed that every sequence of length one will be represented by an XdmItem</. It is quite possible for an XdmValue</ that is not an XdmItem</ to hold a singleton sequence.
Saxon provides two concrete subclasses of XdmItem, namely XdmNode and XdmAtomicValue. Users must not attempt to create additional subclasses.
