This is clearly not an editorial change.

A change to a ďMAYĒ statement *is* a change to RDF.

Adding informative text (e.g., in a Note) would be considered a clarification, and hence not a change to the language itself. It would still be more than an editorial fix.

The AC members are currently reviewing the RDF 1.1 specs and are encouraged to indicate their support (or lack thereof) for sending the documents to REC. Does this process, in theory, still provide Ontotext with an opportunity to object to the current design, request a change, or whatever? Not that we want to encourage such behaviour; itís just that we should mention all the options provided by the process before we reply that itís too late to change anything now.

Best,
Richard
