consumed and discarded. This makes it impossible to deal with other
post types, like xml-rpc or json without resorting to overly complex
"request factory" contortions.

``zope.publisher.http.HTTPCharsets`` was confused by the Zope 2
publisher, which gives misleading information about which headers
it has.
