  Section 14.7.  OPTIONS does not say that a proxy may edit Allow, though
  I can see why you read that into it.

Well, the exact language from section 9.2 (defining OPTIONS) is as follows:

  A 200 response SHOULD include any header fields which indicate
  optional features... (e.g. Allow)....  If the OPTIONS request passes
  through a proxy, the proxy MUST edit the response to exclude those
  options known to be unavailable through that proxy.

That seemed pretty explicit to me, especially since a response to an
OPTIONS request MUST NOT include entity information (or, I presume, an
entity), which doesn't leave much else for the proxy to edit
(Public?).  At any rate, I take it we are agreed that the matter is in
need of clarification.
