referencing a concept scheme as the code list of some referrer's property

This is about SKOS usage in LOD.

Yesterday I sent a post to public-swd-wg@w3.org, but obviously it has
not been distributed, although it can be found in the archive.
http://lists.w3.org/Archives/Public/public-swd-wg/2012Aug/0000.html
public-swd-wg@w3.org isn't very active any more, so public-lod@w3.org
might be a better place.

Best regards,
Thomas

Hi SKOS,

I came across several examples where concept schemes are referenced as
the code list of some property.
Usually this is done by two statements:

ex:property rdfs:range skos:Concept ;
        ex:codeList < [some concept scheme] > .

E.g. Data Cubes and geonames use this pattern, but one uses qb:codeList
to point to the scheme, the other gn:featureClass.

Regarding this, I have two questions:

(1) does someone remember a discussion why concept schemes should not be
expressed as subclasses of skos:Concept?
If subclassing  would have been used, any concept scheme could be
referenced in a single rdfs:type statement of the concept and a single
rdfs:range statement of the referrer.

(2) if there are sufficient reasons to insist in the current patterns,
shouldn't SKOS be extended by a standard property to be used by
referrers when they point to a concept scheme along with  a rdfs:range
statement?

And I add
(3) why do we not have mapping properties to link concept schemes from
different providers?
This cannot be inferred from a given concept mapping, as mapping of some
concepts does not imply mappings of their entire schemes.

Best regards,
Thomas
