Well, it's not as simple as just no encoding -- you still have to deal
with the delimeter problem, right? If your binary data contains
"</foo>", that would be a problem. What you need is an unparsed entity
of sorts for binary data.

Mike, where/to-whom would one submit these? Just the business of
optimizing handling of arbitrary-length element and attribute names can
keep someone quite busy for a while, multi-megabyte base64 sections will
not be a good thing.  

Interestingly, all the discussion focus here is on the on-the-wire
encoding issues -- doesn't seem that anyone feels strongly that binary
data should be passed by reference in some external envelope?
