The notation resembles that of the JSOP move operation (minus clutter)
which it turn reflects the semantics of the JCR move methods: it
includes the name of the target node. See also my definition above:
"Let p, q be paths. Then p:q denotes a move operation where the node at
p is moved to a new node at q."
