Maybe this topic is covered by
http://dev.w3.org/2008/video/mediaann/mediaont-1.0/mediaont-1.0.html#semantic-level-mappings
maybe we should replace "Further it defines semantics-preserving mappings"
with "semantic level mappings", with a link from "semantic level mappings"
to #semantic-level-mappings .
