True, except insofar as the syntax and structure of FPIs contributes to the core issues of persistence, and global uniqueness. The administrative requirements of "formal" names ensure these as long as you follow the rules when assigning identifiers. >There seems to be a complete overlap of the intended goals of FPIs and URNs. >But I think that these two beasts can co-habit.

I'd be happier if I could stop using URLs the _instant_ it was feasible. Allowing URNs as system IDs seems a way to accomplish that. > a) redirect to a local copy, > b) to use documents off-line or > c) use older SGML tools that don't understand URLs. My XML parser can always implement catalogs by looking for URN syntax in the sytem ID, and doing something sensible. -- David I am not a number.
