The class XdmItem represents an item in a sequence, as defined by the XDM data model. An item is either an atomic value or a node.

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 {@link XdmNode} and {@link XdmAtomicValue}. Users must not attempt to create additional subclasses.
