I agree we need to decide if "streaming processors" are explicitly
supported, not supported, or maybe.  While it's not necessarily Occam's
razor, "sax or dom" certainly does seem to separate the issues clearly.

I wonder if it's really an issue; it seems at best an optimization: 
don't start something when you know you're going to fail.  But since you
have to be prepared to handle (internal) failure anyway, I'm not sure
what's gained.

Looks like you cut out some lines you didnt mean to.

Ditto, for the same reasons.
