That the argument cited below appears in the context of names/namespaces/xml-encoding is an artifact of xml's genesis. If one leaves text strings alone for a moment, and permits that, once the document is decoded, the processing can occur on a symbolic level, then the argument has no grounds, as the worrisome interface is relegated to the javadoc archives and never appears in code. Why are people so worried about the "parts of a name" anyway? In lisp code for processing stuff decoded from / encoded into xml there is not a single instance of either (SYMBOL-NAME ...) or (PACKAGE-NAME (SYMBOL-PACKAGE ...)). The only test is (EQ ...). and even those are primarily by virtue of classification for method dispatch. So long as one stays on the "strings" level, however, the need for centralized registration and rectification will prevail... Move up a level: let namespaces themselves be first class objects. Parsers appear in any event to be moving towards interning parsed strings. The processing infrastructure needs operations to manipulate namespaces. A name should not bind an uri; a namespace comprises a collection of names. If implemented in a reasonable fashion, this permits the processor to associate a name with more than one namespace. given that, a process can guarantee the correct mapping from names to symbols and thus to processes without need for a centralized authority.
