SKOS and broaderPartitive, NarrowerInstantive, etc.

The http://www.w3.org/2001/sw/Europe/reports/thes/1.0/guide/20040504/ 
document from 2004 lists subproperties of skos:broader and skos:narrower 
such as skos:broaderPartitive and skos:narrowerGeneric. This document, 
the SKOS-Core 1.0 Guide, also says that it's deprecated and to see 
http://www.w3.org/TR/swbp-skos-core-guide/, which doesn't describe any 
equivalents.

The more recent http://www.w3.org/TR/skos-primer/ document says

    The SKOS approach allows an application designer to create new
    properties to capture this distinction, and to declare them as
    sub-properties of|skos:broader|:

       ex:broaderGeneric rdfs:subPropertyOf skos:broader.
       ex:broaderPartitive rdfs:subPropertyOf skos:broader.
       ex:broaderInstantive rdfs:subPropertyOf skos:broader.

but ex represents an example.com URL.  I had no luck with a search for 
broaderPartitive at schemapedia or 
http://ws.nju.edu.cn/falcons/ontologysearch/ .

Does anyone know if these subproperties of skos:broader and 
skos:narrower ever found a home?
