They might and that might be a good thing. Although I don't know of any
producer that ever produced it since it was for a concept that didn't
really exist in any language. Note that the extra comments didn't end up
in the final spec. All that was officially done was remove the name. All
I am proposing is we do the same since the name should never have been
there in the first place. I'll add a comment instead saying the value is
reserved.
Cheers,
Mark
