indeed but at least by using anchor epoch, the semantics are clear.


I have been wondering about EPSG:6319 (6317), which seems to be a
dynamic frame with a frame reference epoch of 2010.0, but the frame
reference epoch is not part of the EPSG definition.  I don't see how the
datum is tagged as static vs dynamic, or is "no frame reference epoch"
--> static?

Do people think this is correct, or not quite?
