Title: Rewriting header matching text.

The text on matching headers wasn't very clear about what was actually going on. In reality, matching headers is done by the encoder, a process that is invisible from a protocol perspective.

More to the point, there wasn't anything in the draft that dealt with the requirement to downcase header names.
