SAX-model XML parsers still qualify as "out of the box."

By the time you have received an event reporting the blob element, you
have potentially already fed it a chunk containing the <blob/> and some
of your binary data.

(Unless you're handing it characters one by one, or being careful to
never feed chunks which contain a > character except at the end.  Either
is inefficient and hackish.)
