  If I don't understand the extention it doesn't matter whether or not
  I know what headers go with it - I return an error anyway.

  That is my point, and I'll restate it as a question:

  Is the goal of the draft to specify how to require the use of a
  particular extention, or is it to specify how to do dynamically
  loaded extentions?

  The former is important, the latter is an interesting academic

  I didn't see it, but even if it did I don't think that there is any
  requirement that proxies preserve header field order so you can't
  count on it.

  They are for CGI purposes after the prefixes have been removed (or
  are we going to require that CGIs also understand prefixes?).
