-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I guess I want to step back just a bit, and clarify _why_ I've been pushing back on trying to spell out fixup in detail. It's because I think this is a case where the relevant invariants are easy to state and easy for readers to understand, and the mechanisms necessary to achieve those invariants are neither. In such a case, it's a good idea to stop with the invariants. We've got them now in 2.6.1 -- via the combination of "above all, do no harm" (that is, the information which *must* and *should* be preserved other things being equal) and "must serialize to well-formed and ns-well-formed". I have _no_ problem with giving non-normative _guidance_ on our current best guess at how to go about doing the necessary, including pointers to others in the same or similar boats and how _they_ are going about it. I note the (to me at least very positive) example of Schema 1.1's approach to restriction: instead of the huge constructive definition of 1.0, we now have a short statement of the goal ("Restriction is subsumption" == subset of tag sequences accepted) and a non-normative appendix pointing to some external resources which implementors may find helpful. ht - -- Henry S.
