This "extensions" vocabulary was only discussed but does not exist anymore. Similar properties are defined in the new ISO ontology: http://purl.org/iso25964/skos-thes# (broaderInstantive is renamed to iso:broaderInstantial) But they are not subprops of skos:broader. Probably because skos:broader feeds into skos:broaderTransitive, BUT Jutta Lindenthal and others have argued convincingly that you can consider transitive variabts of BG and BP but not BI, nor mixed paths of BG+BP. (Jutta's presentation with Cats and Felines). See discussions around this thread: http://lists.w3.org/Archives/Public/public-esw-thes/2013Nov/0026.html
