We have two ways to go about this: either ignore the value or force it
to be empty. I have a slight preference for the latter, but can live
with the former.

However, in any case, we don't define the concept of HTTP 1.0 Binding.
I would therefore like to propose a friendly amendment, using property
values:

  The value of the {http transfer coding} property is ignored when the
  value of the {http version} property is "1.0".

The solution with forcing it to be empty would look like:

  When the value of the {http version} property is "1.0", the {http
  transfer coding} property MUST be empty.

Cheers,

Hugo
