Unclear representation of geospatial artefacts

[hoehrmann]

As far as I can tell, geospatial artefacts have multiple representations allowed by the schema definitions, all of these paths seem valid:

/m:Structure/m:Structures/s:Codelists[n]/s:Codelist[n]/s:GeoFeatureSetCode[n]/@value
/m:Structure/m:Structures/s:GeographicCodelists[n]/s:GeographicCodelist[n]/s:GeoFeatureSetCode[n]/@value

/m:Structure/m:Structures/s:Codelists[n]/s:Codelist[n]/s:GeoGridCode[n]/s:GeoCell
/m:Structure/m:Structures/s:GeoGridCodelists[n]/s:GeoGridCodelist[n]/s:GeoGridCode[n]/s:GeoCell

The SDMX 3.0.0 Registry specification also does not define special URN prefixes for geospatial artefacts, suggesting they use codelist.Codelist which would suggest the representation under /m:Structure/m:Structures/s:Codelists[n]/ is the intended one, but the examples use the specialized representation, in which case using codelist.Codelist seems inconsistent and one would expect they use URN prefixes of codelist.GeographicCodelist and codelist.GeoGridCodelist.

(In doubt, please handle this as a public review comment on SDMX 3.1 once the comment period begins.)
