Good point. I tried to find them in the current OWL 1.1 drafts (syntax & rdf mapping), but they are silent wrt. these annotations (I don't think they are incompatible though). > btw, with respect to the import discussion, I would point out that > this will have a very large impact if we are not backwards > compatible (several of the large deployed ontologies, esp. in the > govt sector, are managed as somewhat separate pieces with a main > ontology that imports those pieces) , so we should be sure we are > careful to document any changes and if the old mechanism is changed, > to provide a well documented "fix" I agree, and I believe this caution is broadly shared within the WG (cf.
