And, to paraphrase, how is that not look-it-up(DNS,locator

Obviously, I don't envision modal dialogs and whatnot to ask the user
permission to get the extension. Simply, if the extension module is not
present and the processor hasn't been configured to download it
automatically, then it dies requesting it's dependency. If it has been
configured to automatically download extensions then it uses the RDDL
document to get the most appropriate module.
Embedding ties one to an implementation language for a given extension. I
don't understand the advantages this could have.
