Envelope, encoding, mustUnderstand qnames, DTD indicator.  Note that's
just a list of the bits worth considering.  I'm not suggesting we make
them all parameters.

Yes, I did want this with the "envelope" parameter, as I corrected
myself earlier in this thread.

Sure, in the same way that the root element may have a namespace that
is recognized, but some contained element may be from an unrecognized
namespace.  But there's still value in exposing the root namespace, as
long as the way it is exposed doesn't suggest that it's the only
namespace in use.  The same could work for encodingStyle.

My earlier question to you, which I thought you answered in the
affirmative, was whether encodingStyle was typically used once at or
near the root of the body block.  To me, that says that it would
therefore be useful to allow implementations to support this parameter.

Including "action"?  I thought Henrik described its value well.  I had
suggested the same thing a few months earlier too.
