wsgiref.validate makes also other assumptions about a WSGI application
that are not required by the WSGI PEP.

As an example it reports as an error the presence in the environ
dictionary of HTTP_CONTENT_TYPE and HTTP_CONTENT_LENGTH, but the PEP
says nothing about this, and CGI [1] says:
""""The server may exclude any headers which it has already processed,
such as Authorization, Content-type, and Content-length. If necessary,
the server may choose to exclude any or all of these headers if
including them would exceed any system environment limits."""

P.S.:
the link "http://cgi-spec.golux.com/draft-coar-cgi-v11-03.txt" is broken.
