FSIs were discussed at the beginning. A decision was made that they were better left for later, and I agree. A decision was also made that all system identifiers would have an implicit FSI identifier of <URL>, which I also think is usually a good idea. This allows FSIs to be added later, and any unlabeled system ID is implied to have <URL>. What I was suggesting on the SIG was that for system identifiers in notation declarations, the assumed FSI label would be <mimetype>. As Rick pointed out, this is legal HyTime 2 FSI notation, and would be very useful. However, the WG has made its decision. I believe that XML authors are largely going to refer to images simply by URLs instead of entities; in that case, file system associations or HTTP headers can be used to ascertain the entity's type. In cases where NDATA entities are used, I would recommend that XML implementors ignore the system identifier of the notation, and make their decision based on the entity itself. -Chris -- <!NOTATION SGML.Geek PUBLIC "-//Anonymous//NOTATION SGML Geek//EN"> <!ENTITY crism PUBLIC "-//O'Reilly//NONSGML Christopher R.
