#168: understanding CC directives

p6 currently states:

  The "Cache-Control" general-header field is used to specify directives that
  &MUST; be obeyed by all caches along the request/response chain.

but as Jamie points out in <http://trac.tools.ietf.org/wg/httpbis/trac/ticket/168>, this doesn't work so well with extension CC directives.

I think the intent is preserved with:

"""
  The "Cache-Control" general-header field is used to specify directives for caches along the request/response chain. HTTP/1.1 caches
MUST obey the requirements of the Cache-Control directives defined in this section. See [ref to CC extensions] for information about how Cache-Control directives defined elsewhere are handled.
"""

Thoughts?
