mode= and type= not orthogonal

[Tim Bray <tbray@xxxxxxxxxxxxxx>]

The title says it.

I get the impression that the *only* scenario in which you would use 
mode="escaped" is in the case where you're providing 
maybe-non-wellformed HTML.  You might be able to conjure up a 
counter-example, but if we're putting this in to support a specific 
fairly-kludgy legacy behavior, let's be upfront about this.

So.... either we say mode="escaped" implies type="text/html".

Or maybe rename it to mode="legacy-html"  -Tim
