ItemId identifies an item using a combination of unique ID
and path. There are three basic forms of an ItemId. The following
table shows each of the allowed combinations where an X in
the column indicates that a value is set and a - indicates
that the value is
||The item can be identified with a unique ID. In most cases such an item
is also mix:referenceable but there is no restriction in that respect. An
SPI implementation may also use a unique ID to identify non-referenceable nodes.
Whether a node is referenceable is purely governed by its node type or
the assigned mixin types. Note, that the format of the ID it is left to the
||The item can not be identified with a unique ID and none of its ancestors
can be identified with a unique ID. The item is identified by an absolute path.

getUniqueID() returns the unique ID of the nearest ancestor, which
can be identified with a unique ID. The relative path provides a navigation
path from the above mentioned ancestor to the item identified by the
