add time range semantics. Maybe with support for the
density/distribution of the points available? Maybe with
ability to subsample? When contain list of actual times in DQC
rather than an abstraction?
extend spatial range semantics. Look at GML, see 2.1.2 spec
at http://www.opengis.org/techno/specs/02-069/GML2-12.html,
possibly for time range as well.
