Quick follow up. With regard to Mark's proposal at [1]: PROPOSAL So to bring everything together, the proposal is: (a) RDFa should add support for URIs in attributes that currently only support CURIEs; (b) authors should be encouraged to use safe-CURIEs in those attributes; (c) but since ordinary CURIEs may still be used, we should differentiate by saying that anything appearing before a colon, that is not a mapped prefix, is a protocol. I disagree with (b). I don't think there is any need for this. If the processing rules are handling this, then in these contexts there is no need to use a safe curie. On the other hand, the TAG will have a cow if we permit URIs and CURIEs in the same place. That was their principle objection to the CURIE spec. How do we overcome that hurdle?
