Ruby Annotation for I18N'd thes labels

Quick thought, hope it makes sense:
http://www.w3.org/TR/ruby/

some  chunks of text (eg. Japanese) in a SKOS db might need to
contain Ruby markup. In RDF, we distinguish between XML Literal 
literals and 'plain' literals; the latter don't have markup.

Can SKOS accomodate this currently?
