Seems reasonable and I tend to agree. I haven't thought enough about the
consequences of doing this yet to give a definite answer.

Yes, that's still being done. We change the behavior of @id in the body but
not in the context. Relative IRIs are not allowed in the context so there's
no risk of a clash.

You are probably right. Could you create an issue for this so that we can
vote on it. I think since the change is so trivial we can resolve this even
before the next telecon. Thanks.


Have a nice weekend,
