[gdal-dev] in WKT, is "unknown datum" = "specified perfect spheroid" with no additional shifts & modificati​ons ?

[Yasin Selçuk Berber]

Hi.

i want to be sure that, in a WKT, if the datum is specified as "unknown",
does that mean;
the datum is same as "the given perfect spheroid in WKT" with no specific
adjustments to match real earth, bulges ... etc ?

thanks
