    2323   * [http://kahlua.eecs.jacobs-university.de:8080/def/crs/OGC/0/AnsiDate ANSI date] (`OGC:AnsiDate`) : linear count of days (labelled `'ansi'`) since 1^st^ of January 1601, 00h00 UTC (note that decimal coordinates are possible to reference fraction of the day).
    24    * [http://kahlua.eecs.jacobs-university.de:8080/def/crs/OGC/0/Temporal?expand=none parametrized temporal CRS] (`OGC:Temporal`) : parametrized CRS for the user-friendly definition of a custom T-CRS: it resolves to a concrete definition of T-CRS as long as the ''epoch'' and the ''UoM'' are explicitly set in the query of the URI (and optionally an axis label and an axis direction: defaults are `'t'` and `'future'`). !UoMs can be defined as either [http://unitsofmeasure.org/ucum.html UCUM] `c/s` codes or actionable URIs pointing to valid GML definition of !UoMs; UCUM codes or URIs like ''http://www.opengis.net/def/uom/UCUM/0/<code>'' (which the OGC SISSVoc resolver redirects to the UCUM web page) or codes are suggested here: our ISO timestamp parser relies on UCUM codes too.
