The updated "finding" still seems to assume that "GET with
body" has something to do with solving the problem of insuring
that important resources should be accessible via a URL. But
if the data to access the resource is in the body (or in any headers
or anywhere other than the URL itself), then the goal isn't
accomplished. There's no difference between POST and GET-with-body
as far as accomplishing the stated objective.

Does not what? Maybe I am not reading your 'diff' notation correctly.

It's not exactly right to talk about a 'content type' when encoding data
in a URI. The awkward name 'application/x-www-form-urlencoded' was made
up for creating a MIME body that is encoded using the URI mechanism,
but for talking about the URI-encoding method, it's just the URI

It's not in the XForms charter to solve this problem, I don't think.
