Is there a regular expression for geoSystem in XML Schema? Perhaps there should be?

appreciate the details gentlemen, am now tracking.  thank you.

am still confused regarding status tho... the Mantis issue is confirmed but not resolved; first Note says: "'N' should definitely be allowed."  Other followups in the issue indicate that "N" should be allowed.  Incidentally have we looked at other formats usage regarding UTM and N?  Being consistent is likely helpful.

i think this is why the content wasn't reconciled earlier, because the Mantis issue is still open.

looking forward to resolving the issue and finalizing content/converter/schema.

The V3.3 of the standard only permits an optional “S” to indicate southern hemisphere. The northern hemisphere “N” is not permitted. It is assumed by default if there is no “S”.

This problem was only identified because of the greater expressive power of JSON schema over the corresponding XML schema. The JSON schema was written to fully validate the geoSystem field in accordance with the standard. The Schematron should also be able to do this. Does it?
