Suggestion from Oracle (Dana Florescu) presentation at #xmlprague.
Idea being to ask for a specific version or nodeset existant
at a specific time in the past!
Great idea, though I propose it be a forward axis!
http://www.dbis.ethz.ch/research/publications/timemachinexml.pdf
we also introduce the following axes: rst::,
earlier::, past::, past-or-current::, current::, later::, future::,
future-or-current::, last::, all-times:: and local::. For exam-
ple, later::* navigates to the next version of the node time-
line to which the current node belongs or the empty sequence
if it does not exist.
Which is all relative to a node which has a position on
the timeline, which may be in the past, to give you a 'forward'/future axis!
Some neat ideas.
