I thought the intent was something like: someone developing a new XML vocabulary wants to include HLink semantics, so includes an HLink mapping along with the rest of the vocabulary specification (schema, documentation, etc.) Application developers who want to use the new vocabulary consult the HLink mapping when building their own application. Something like how WSDL works -- web service clients don't download WSDL at runtime, the _developer_ does when _building_ the client. Of course with this approach generic web browsers can't automatically discover the HLink links in arbitrary XML files, but it's not clear that this is even a requirement. We don't expect browsers to automatically figure out how to process *any* random XML documents they happen to download, only the ones that use a supported vocabulary. > SELF-CONTAINED INFORMATION: > In disconnected scenarios or situations where the document is being read by a > human all the information about the document is not readily available.

Again, I don't think this is even a requirement. _No_ XML document is completely self-contained; we always rely on the producer and consumer sharing some knowledge of how to process the vocabulary. --Joe English jenglish@f...
