Does draft proposal I posted for mapping [1] bring an answer to your 
question? The idea would be expressing conceptual mapping across concept 
schemes trying to re-use the existing SKOS semantic relationships when 
possible ...

I think this is covered by ISSUE-36 ConceptSchemeContainment 
http://www.w3.org/2006/07/SWD/track/issues/36
