Very true. Hence the need for URNs, or URLs managed as URNs. No formal property whatever *guarantees* persistence: persistence is a property of how humans behave (in the case of MIME, how Jon Postel behaved and how his successors are expected to behave). > External X10 data could, however, change its > identification without some lucky person or program tracking down every > reference to it in documents to reflect the change. Again, I believe notations (whether used directly, or mediated through schemas/DTDs) are far more useful when governing elements than when describing whole remote documents. > Putting the notations > in documents creates a maintenance headache that shouldn't be > underestimated.

Okay, I'm convinced now that we really need the MIME-types-as-notations DTD fragment.

Safe central registries can be *created* on top of the WWW (as the PURL folks are doing) without sacrificing the utility of ad-hoc-but-globally-accessible universal names for things. -- John Cowan http://www.ccil.org/~cowan cowan@c...
