[Appendix G](#appendix-g-geospatial-notes). Parameterized by CRS C. If not
specified, C is `OGC:CRS84`. |

Notes:
1. Timestamp values _without time zone_ represent a date and time of day
regardless of zone: the time value is independent of zone adjustments
(`2017-11-16 17:10:34` is always retrieved as `2017-11-16 17:10:34`).
2. Timestamp values _with time zone_ represent a point in time: values are
stored as UTC and do not retain a source time zone (`2017-11-16 17:10:34 PST`
is stored/retrieved as `2017-11-17 01:10:34 UTC` and these values are
considered identical).
3. Character strings must be stored as UTF-8 encoded byte arrays.
